photobox

A lightweight CSS3 image & video viewer that is pretty to look and and easy to use.

Demo page, Blog post

Benefits

  • Lightweight! jquery.photobox.js is only 5kb (gziped & minified)
  • Silky-smooth, hardware accelerated, CSS3 transitions and animations (for better performance)
  • Support videos via iframe embedding
  • Stunning UI and user-friendly UX
  • Built so everything could be changed directly from the CSS
  • Observes DOM changes (if images were added/removed) and adapt accordingly
  • CSS3 pre-loader, tailored-made
  • Uses event-delegation on all thumbnails clicks (obviously...)
  • Uses HTML5 History to update location with the currently viewed image
  • The only image is a pre-loader animation for old IE. For the rest, no images at all!
  • Browsers support: IE8+ (graceful degradation), Modern browsers

Functionality

  • Images/videos can be zoomed in and out with mousewheel and navigated using mousemove to move around
  • Bottom row of thumbnails, navigated by mouse movement, can be resized using the mousewheel
  • Shows the image's 'alt' or 'title' attribute text at the bottom
  • Indicate the index of the current viewed image in relation to the total, like so: (36/100)
  • Touch-friendly swipe left/right to change image. Swipe up/down to toggle the thumbnails stripe
  • Supports looping after first and last images
  • Auto-playing of images at a set interval (see "time" in Settings)
  • Supports keyboard keys for navigation and closing the gallery view
  • In case there was an error loading an image, a message is shown, which can be configured via CSS

Basic use-case example:

<div id='gallery'>
    <a href="http://www.somedomain.com/images/image1_large.jpg">
        <img src="http://www.somedomain.com/images/image1_small.jpg" title="photo1 title">
    </a>
    <a href="http://www.somedomain.com/images/image2_large.jpg">
        <img src="http://www.somedomain.com/images/image2_small.jpg" alt="photo2 title">
    </a>
    <a href="http://www.somedomain.com/images/image3_large.jpg">
        <img src="http://www.somedomain.com/images/image3_small.jpg" title="photo3 title">
    </a>
    <a href="http://www.somedomain.com/images/image4_large.jpg">
        <img src="http://www.somedomain.com/images/image4_small.jpg" alt="photo4 title" data-pb-captionLink='Google website[www.google.com]'>
    </a>
    <a href="http://www.youtube.com/embed/W3OQgh_h4U4" rel="video">
        <img src="http://img.youtube.com/vi/W3OQgh_h4U4/0.jpg" title="PEOPLE ARE AWESOME 2013 FULL HD ">
    </a>
</div>
...
...
...
<script>
    // applying photobox on a `gallery` element which has lots of thumbnails links. Passing options object as well:
    //-----------------------------------------------
    $('#gallery').photobox('a',{ time:0 });

    // using a callback and a fancier selector
    //----------------------------------------------
    $('#gallery').photobox('li > a.family',{ time:0 }, callback);
    function callback(){
       console.log('image has been loaded');
    }

    // destroy the plugin on a certain gallery:
    //-----------------------------------------------
    $('#gallery').photobox('destroy');

    // re-initialize the photbox DOM (does what Document ready does)
    //-----------------------------------------------
    $('#gallery').photobox('prepareDOM');
</script>

Videos

<div id='gallery'>
    ...
    <a href="http://www.youtube.com/embed/W3OQgh_h4U4" rel="video">
        <img src="http://img.youtube.com/vi/W3OQgh_h4U4/0.jpg" title="PEOPLE ARE AWESOME 2013 FULL HD ">
    </a>
    ...
</div>

A video link must have the rel attribute with the value of video. The url of the link must be the iframe embed (youtube, vimeo, etc.) And inside you can put a thumbnail of the video (of course)

Changing Effects Is Easy!

Advanced CSS users would know this, but for rest, you can just copy the below example code at the end of the photobox.css file:

#pbOverlay .imageWrap img, #pbOverlay.hide .imageWrap img.prepare{ transform:rotateX(90deg); -webkit-transform:rotateX(90deg); -ms-transform:rotateX(90deg); }
#pbOverlay.hide .imageWrap img{ transform:rotateX(-90deg); -webkit-transform:rotateX(-90deg); transform:none\9; opacity:.6; }

Basicly, I'm just playing with the image's style state; before it's appearance and during hiding, so you can do whatever here really.

Custom Caption Links

you can add your own links along with the title or alt attributes texts, just add data-pb-captionLink to the image thumbnail:
data-pb-captionLink='Google website[www.google.com]'

Overriding defaults

It is always recommended not to touch the source code directly, because then you will have a version which is out-of-sync with any future version, and you might face some difficult merges with your own changes. So, if you want to change some stuff, I would recommend creating another file, typically called jquery.photobox.mod.js. This good practice also applies for the CSS file.

Example:

/*!
    photobox modifications,
    after it has been loaded
*/

(function(){
    "use strict";
    // adding a "userInfo" HTML to the overlay container:
    var userInfo = $('<div class="userInfo"><img><span></span></div>');

    var photoboxCallbacks = (function(){
        // do something
    })();

    // change defaults:
    window._photobox.defaults.time = 0;
    window._photobox.defaults.beforeShow = photoboxCallbacks.beforeShow;

    // append "userInfo" after DOMReady has been fired
    // (the overlay won't exist in the DOM before then)
    $(document).ready(function(){
        var overlay = $('#pbOverlay');

        // add class to the default close button
        $('#pbCloseBtn').addClass('btn');

        // append user info DOM structure
        overlay.append(userInfo);
    });
})();
