customizable image and video +gallery, carousel and lightbox, optimized for both mobile and desktop web +browsers. +It features swipe, mouse and keyboard navigation, transition effects, slideshow +functionality, fullscreen support and on-demand content loading and can be +extended to display additional content types. + +## Setup + +### Lightbox setup + +Copy the **css**, **img** and **js** directories to your website. + +Include the Gallery stylesheet in the head section of your webpage: + +```html + +``` + +Add the following HTML snippet with the Gallery widget to the body of your +webpage: + +```html + + +``` + +Include the Gallery script at the bottom of the body of your webpage: + +```html + +``` + +Create a list of links to image files, optionally with enclosed thumbnails and +add them to the body of your webpage, before including the Gallery script: + +```html + +``` + +Add the following JavaScript code after including the Gallery script, to display +the images in the Gallery lightbox on click of the links: + +```html + +``` + +### Controls + +To initialize the Gallery with visible controls, add the CSS class +**blueimp-gallery-controls** to the Gallery widget: + +```html + +``` + +### Carousel setup + +To display the images in an inline carousel instead of a lightbox, follow the +[lightbox setup](#lightbox-setup) and add the CSS class +**blueimp-gallery-carousel** to the Gallery widget and remove the child element +with the **close** class, or add a new Gallery widget with a different **id** to +your webpage: + +```html + + +``` + +Add the following JavaScript code after including the Gallery script to +initialize the carousel: + +```html + +``` + +## Keyboard shortcuts + +The Gallery can be controlled with the following keyboard shortcuts: + +- **Return**: Toggle controls visibility. +- **Esc**: Close the Gallery lightbox. +- **Space**: Toggle the slideshow (play/pause). +- **Left**: Move to the previous slide. +- **Right**: Move to the next slide. + +Please note that setting the **carousel** option to **true** disables the +keyboard shortcuts by default. + +## Options + +### Default options + +The following

following are equivalent: + +```js +var options = { + container: '#blueimp-gallery' +} +``` + +```js +var options = { + container: document.getElementById('blueimp-gallery') +} +``` + +The **slidesContainer**, **titleElement** and **indicatorContainer** options can +also be defined using a tag name, which selects the first tag of this kind found +inside of the widget container: + +```js +var options = { + slidesContainer: 'div', + titleElement: 'h3', + indicatorContainer: 'ol' +} +``` + +It is also possible to define the container and element options with a more +complex +[querySelector](https://developer.mozilla.org/en-US/docs/Web/API/document.querySelector), +which is supported by IE8+ and all modern web browsers. + +If the helper script is replaced with [jQuery](https://jquery.com/), the +container and element options can be any valid jQuery selector. + +### Property options + +The options ending with "Property" define how the properties of each link +element are accessed. +For example, the **urlProperty** is by default set to **href**. This allows to +define link elements with **href** or **data-href** attributes: + +```html + +``` + +If the links are passed as JavaScript array, it is also possible to define +nested property names, by using the native JavaScript accessor syntax for the +property string: + +```js +blueimp.Gallery( + [ + { + data: { urls: ['https://example.org/images/banana.jpg'] } + }, + { + data: { urls: ['https://example.org/images/apple.jpg'] } + } + ], + { + urlProperty: 'data.urls[0]' + } +) +``` + +## API + +### Initialization + +The blueimp Gallery can be initialized by simply calling it as a function with +an array of links as first argument and an optional options object as second +argument: + +```js +var gallery = blueimp.Gallery(links, options) +``` + +The links array can be a list of URL strings or a list of objects with URL +properties: + +```js +var gallery = blueimp.Gallery([ + 'https://example.org/images/banana.jpg', + 'https://example.org/images/apple.jpg', + 'https://example.org/images/orange.jpg' +]) +``` + +```js +var gallery = blueimp.Gallery([ + { + title: 'Banana', + href: 'https://example.org/images/banana.jpg', + type: 'image/jpeg', + thumbnail: 'https://example.org/thumbnails/banana.jpg' + }, + { + title: 'Apple', + href: 'https://example.org/images/apple.jpg', + type: 'image/jpeg', + thumbnail: 'https://example.org/thumbnails/apple.jpg' + } +]) +``` + +The URL property name defined by each list object can be configured via the +**urlProperty** option. By default, it is set to **href**, which allows to pass +a list of HTML link elements as first argument. + +For images, the **thumbnail** property defines the URL of the image thumbnail, +which is used for the indicator navigation displayed at the bottom of the +Gallery, if the controls are visible. + +The object returned by executing the Gallery function (the **gallery** variable +in the example code above) is a new instance of the Gallery and allows to access +the public [API methods](#api-methods) provided by the Gallery. +The Gallery initialization function returns **false** if the given list was +empty, the Gallery widget is missing, or the browser doesn't pass the +functionality test. + +### API methods + +The Gallery object returned by executing the Gallery function provides the +following public API methods: + +```js +// Return the current slide index position: +var pos = gallery.getIndex() + +// Return the total number of slides: +var count = gallery.getNumber() + +// Move to the previous slide: +gallery.prev() + +// Move to the next slide: +gallery.next() + +// Move to a slide index with the (optional) duraction speed in milliseconds: +gallery.slide(index, duration) + +// Start an automatic slideshow with the interval in milliseconds (optional): +gallery.play(interval) + +// Stop the automatic slideshow: +gallery.pause() + +// Add additional slides after Gallery initialization: +gallery.add(list) + +// Close and deinitialize the Gallery: +gallery.close() +``` + +### Videos + +#### HTML5 video player + +The Gallery can be initialized with a list of videos instead of images, or a +combination of both: + +```js +blueimp.Gallery([ + { + title: 'Fruits', + href: 'https://example.org/videos/fruits.mp4', + type: 'video/mp4', + poster: 'https://example.org/images/fruits.jpg' + }, + { + title: 'Banana', + href: 'https://example.org/images/banana.jpg', + type: 'image/jpeg', + thumbnail: 'https://example.org/thumbnails/banana.jpg' + } +]) +``` + +The Gallery uses the **type** property to determine the content type of the +object to display. +If the type property is empty or doesn't exist, the default type **image** is +assumed. +Objects with a video type will be displayed in a +[HTML5 video element](https://developer.mozilla.org/en-US/docs/Web/HTML/Element/video) +if the browser supports the video content type. + +For videos, the **poster** property defines the URL of the poster image to +display, before the video is started. + +#### Multiple video sources + +To provide multiple video formats, the **sources** property of a list object can +be set to an array of objects with **href** and **type** properties for each +video source. The first video format in the list that the browser can play will +be displayed: + +```js +blueimp.Gallery([ + { + title: 'Fruits', + type: 'video/*', + poster: 'https://example.org/images/fruits.jpg', + sources: [ + { + href: 'https://example.org/videos/fruits.mp4', + type: 'video/mp4' + }, + { + href: 'https://example.org/videos/fruits.ogg', + type: 'video/ogg' + } + ] + } +]) +``` + +It is also possible to define the video sources as data-attribute on a link +element in [JSON](https://developer.mozilla.org/en-US/docs/JSON) array format: + +```html + +``` + +#### YouTube + +The Gallery can display [YouTube](https://www.youtube.com/) videos for Gallery +items with a **type** of **text/html** and a **youtube** property (configurable +via [YouTube options](#youtube-options)) with the YouTube video-ID: + +```js +blueimp.Gallery([ + { + title: 'A YouYube video', + href: 'https://www.youtube.com/watch?v=VIDEO_ID', + type: 'text/html', + youtube: 'VIDEO_ID', + poster: 'https://img.youtube.com/vi/VIDEO_ID/maxresdefault.jpg' + }, + { + title: 'Banana', + href: 'https://example.org/images/banana.jpg', + type: 'image/jpeg', + thumbnail: 'https://example.org/thumbnails/banana.jpg' + } +]) +``` + +If the `href` and `poster` properties are undefined, they are set automatically +based on the video ID. + +Please note that the Gallery YouTube integration requires a browser with +[postMessage](https://developer.mozilla.org/en-US/docs/Web/API/window.postMessage) +support, which excludes IE7. + +#### Vimeo + +The Gallery can display [Vimeo](https://vimeo.com/) videos for Gallery items +with a **type** of **text/html** and a **vimeo** property (configurable via +[Vimeo options](#vimeo-options)) with the Vimeo video-ID: + +```js +blueimp.Gallery([ + { + title: 'A Vimeo video', + href: 'https://vimeo.com/VIDEO_ID', + type: 'text/html', + vimeo: 'VIDEO_ID', + poster: 'https://secure-b.vimeocdn.com/ts/POSTER_ID.jpg' + }, + { + title: 'Banana', + href: 'https://example.org/images/banana.jpg', + type: 'image/jpeg', + thumbnail: 'https://example.org/thumbnails/banana.jpg' + } +]) +``` + +If the `href` property is undefined, it is set automatically based on the video +ID. + +Please note that the Gallery Vimeo integration requires a browser with +[postMessage](https://developer.mozilla.org/en-US/docs/Web/API/window.postMessage) +support, which excludes IE7. + +### Additional Gallery elements + +It is possible to add additional elements to the Gallery widget, e.g. a +description label. + +First, add the desired HTML element to the Gallery widget: + +```html + +``` + +Next, add the desired element styles to your CSS file: + +```css +.blueimp-gallery > .description { + position: absolute; + top: 30px; + left: 15px; + color: #fff; + display: none; +} +.blueimp-gallery-controls > .description { + display: block; +} +``` + +Then, add the additional element information to each of your links: + +```html + +``` + +Finally, initialize the Gallery with an onslide callback option, to set the +element content based on the information from the current link: + +```js +blueimp.Gallery(document.getElementById('links'), { + onslide: function(index, slide) { + var text = this.list[index].getAttribute('data-description'), + node = this.container.find('.description') + node.empty() + if (text) { + node[0].appendChild(document.createTextNode(text)) + } + } +}) +``` + +### Additional content types + +By extending the Gallery prototype with new factory methods, additional content +types can be displayed. By default, blueimp Gallery provides the +**imageFactory** and **videoFactory** methods for **image** and **video** +content types respectively. + +The Gallery uses the **type** property of each content object to determine which +factory method to use. The **type** defines the +[Internet media type](https://en.wikipedia.org/wiki/Internet_media_type) of the +content object and is composed of two or more parts: A type, a subtype, and zero +or more optional parameters, e.g. **text/html; charset=UTF-8** for an HTML +document with UTF-8 encoding. +The main type (the string in front of the slash, **text** in the example above) +is concatenated with the string **Factory** to create the factory method name, +e.g. **textFactory**. + +#### Example HTML text factory implementation + +Please note that the textFactory script has to be included after the core +Gallery script, but before including the [YouTube](#youtube) and [Vimeo](#vimeo) +integration plugins, which extend the textFactory implementation to handle +YouTube and Vimeo video links. + +Please also note that although blueimp Gallery doesn't require +[jQuery](https://jquery.com/), the following example uses it for convenience. + +Extend the Gallery prototype with the **textFactory** method: + +```js +blueimp.Gallery.prototype.textFactory = function(obj, callback) { + var $element = $('
') + .addClass('text-content') + .attr('title', obj.title) + $.get(obj.href) + .done(function(result) { + $element.html(result) + callback({ + type: 'load', + target: $element[0] + }) + }) + .fail(function() { + callback({ + type: 'error', + target: $element[0] + }) + }) + return $element[0] +} +``` + +Next, add the **text-content** class to the Gallery CSS: + +```css +.blueimp-gallery > .slides > .slide > .text-content { + overflow: auto; + margin: 60px auto; + padding: 0 60px; + max-width: 920px; + text-align: left; +} +``` + +With the previous changes in place, the Gallery can now handle HTML content +types: + +```js +blueimp.Gallery([ + { + title: 'Noodle soup', + href: 'https://example.org/text/noodle-soup.html', + type: 'text/html' + }, + { + title: 'Tomato salad', + href: 'https://example.org/text/tomato-salad.html', + type: 'text/html' + } +]) +``` + +### jQuery plugin + +#### jQuery plugin setup + +The blueimp Gallery jQuery plugin registers a global click handler to open links +with **data-gallery** attribute in the Gallery lightbox. + +To use it, follow the [lightbox setup](#lightbox-setup) guide, but replace the +minified Gallery script with the jQuery plugin version and include it after +including [jQuery](https://jquery.com/): + +```html + + +``` + +Next, add the attribute **data-gallery** to your Gallery links: + +```html + +``` + +The onclick handler from the [lightbox setup](#lightbox-setup) guide is not +required and can be removed. + +#### HTML5 data-attributes + +Options for the Gallery lightbox opened via the jQuery plugin can be defined as +[HTML5 data-attributes](https://api.jquery.com/data/#data-html5) on the Gallery +widget container. + +The jQuery plugin also introduces the additional **filter** option, which is +applied to the Gallery links via +[jQuery's filter method](https://api.jquery.com/filter/) and allows to remove +duplicates from the list: + +```html + +``` + +This will initialize the Gallery with the option **startSlideshow** set to +**true**. +It will also filter the Gallery links so that only links with an even index +number will be included. + +#### Container ids and link grouping + +If the **data-gallery** attribute value is a valid id string (e.g. +"#blueimp-gallery"), it is used as container option. +Setting **data-gallery** to a non-empty string also allows to group links into +different sets of Gallery images: + +```html + + +``` + +This will open the links with the **data-gallery** attribute +**#blueimp-gallery-fruits** in the Gallery widget with the id +**blueimp-gallery-fruits**, and the links with the **data-gallery** attribute +**#blueimp-gallery-vegetables** in the Gallery widget with the id +**blueimp-gallery-vegetables**. + +#### Gallery object + +The gallery object is stored via +[jQuery data storage](https://api.jquery.com/category/miscellaneous/data-storage/) +on the Gallery widget when the Gallery is opened and can be retrieved the +following way: + +```js +var gallery = $('#blueimp-gallery').data('gallery') +``` + +This gallery object provides all methods outlined in the API methods section. + +#### jQuery events + +The jQuery plugin triggers Gallery events on the widget container, with event +names equivalent to the gallery [event callbacks](#event-callbacks): + +```js +$('#blueimp-gallery') + .on('open', function(event) { + // Gallery open event handler + }) + .on('opened', function(event) { + // Gallery opened event handler + }) + .on('slide', function(event, index, slide) { + // Gallery slide event handler + }) + .on('slideend', function(event, index, slide) { + // Gallery slideend event handler + }) + .on('slidecomplete', function(event, index, slide) { + // Gallery slidecomplete event handler + }) + .on('close', function(event) { + // Gallery close event handler + }) + .on('closed', function(event) { + // Gallery closed event handler + }) +``` + +## Requirements + +blueimp Gallery doesn't require any other libraries and can be used standalone +without any dependencies. + +You can also use the individual source files instead of the standalone minified +version: + +```html + + + + + + + + + + + +``` + +The helper script can be replaced by [jQuery](https://jquery.com/) v. 1.7+. +The fullscreen, indicator, video, youtube and vimeo source files are optional if +their functionality is not required. + +The [jQuery plugin](#jquery-plugin) requires [jQuery](https://jquery.com/) v. +1.7+ and the basic Gallery script, while the fullscreen, indicator, video, +youtube and vimeo source files are also optional: + +```html + + + + + + + + +``` + +Please note that the jQuery plugin is an optional extension and not required for +the Gallery functionality. + +## Browsers + +blueimp Gallery has been tested with and supports the following browsers: + +### Desktop browsers + +- Google Chrome 14.0+ +- Apple Safari 4.0+ +- Mozilla Firefox 4.0+ +- Opera 10.0+ +- Microsoft Internet Explorer 7.0+ +- Microsoft Edge 41.0+ + +_Please note:_ +Microsoft Edge version 40 has a query selector bug which prevents the Gallery +lightbox demo from opening the image view.
