/**
 * jQuery Lightbox
 * Version 0.5 - 11/29/2007
 * @author Warren Krewenki
 *
 * Changes by:
 * @author Krzysztof Kotowicz <koto at webworkers dot pl>:
 *  - bugfix: multiple instances of Lightbox galleries allowed
 *    (using opts variable instead of $.fn.lightbox.defaults)
 *  - bugfix: use var for local variables in a few functions
 *  - added support for navbarOnTop setting
 *  - added support for displayTitle setting
 *  - added support for slideNavBar setting (with slideNavBarSpeed)
 *  - added support for displayHelp setting
 *  - added support for fitToScreen setting (ported Lightbox VinDSL hack)
 *    (see http://www.huddletogether.com/forum/comments.php?DiscussionID=307)
 *  - plugin now uses jQuery.width() and jQuery.height()
 *  - removed eval() calls
 *  - removed destroyElement - uses jQuery.remove()
 *  - use of prevLinkText, nextLinkText and help
 *  - all strings are now placed in opts.strings to allow for customization/translation
 *
 * Based on Lightbox 2 by Lokesh Dhakar (http://www.huddletogether.com/projects/lightbox2/)
 * Originally written to make use of the Prototype framework, and Script.acalo.us, now altered to use jQuery.
 *
