<?php
/**
 * Elgg lightbox
 *
 * Usage
 * ---------------
 * Call elgg_load_js('lightbox') and elgg_load_css('lightbox'). 
 * Then apply the class elgg-lightbox to links.
 *
 * 
 * Advanced Usage
 * -----------------
 * Elgg is distributed with the Colorbox jQuery library. Please go to
 * http://www.jacklmoore.com/colorbox for more information on the options of this lightbox.
 * 
 * You can change global options by overriding the js/lightbox/settings view.
 *
 * You may apply colorbox options to an individual .elgg-lightbox element
 * by setting the attribute data-colorbox-opts to a JSON settings object. You
 * can also set options in the elgg.ui.lightbox.bind() method, but data
 * attributes will take precedence.
 * 
 * To support a hidden div as the source, add "inline: true" as a 
 * data-colorbox-opts option. For example, using the output/url view, add:
 *    'data-colorbox-opts' => '{"inline": true}',
 * 
 * 
 * Overriding with a different lightbox
 * -------------------------------------
 * In a plugin, override this view and override the registration for the
 * lightbox JavaScript and CSS (@see elgg_views_boot()).
