/**
* Galleria (http://monc.se/kitchen)
*
* Galleria is a javascript image gallery written in jQuery.
* It loads the images one by one from an unordered list and displays thumbnails when each image is loaded.
* It will create thumbnails for you if you choose so, scaled or unscaled,
* centered and cropped inside a fixed thumbnail box defined by CSS.
*
* The core of Galleria lies in it's smart preloading behaviour, snappiness and the fresh absence
* of obtrusive design elements. Use it as a foundation for your custom styled image gallery.
*
* MAJOR CHANGES v.FROM 0.9
* Galleria now features a useful history extension, enabling back button and bookmarking for each image.
* The main image is no longer stored inside each list item, instead it is placed inside a container
* onImage and onThumb functions lets you customize the behaviours of the images on the site
*
* Tested in Safari 3, Firefox 2, MSIE 6, MSIE 7, Opera 9

* Version 1.0

/*********************************************************************
MODIFIED TO WORK WITH WORDPRESS
What was changed?
* The addition of the first line of code '$j=jQuery.noConflict();' and
* I manually went through and replaced all '$' jQuery references with
* '$j'. Also, removed '(jQuery)' which was tacked on to the end of
* the main (currently line 400, there is also a note there).
* Nothing else was changed.
* Note that the jQuery history plugin (at the end of this file)
* is already using 'jQuery' rather than '$'. I made no changes to the
* plugin, nor did I test the plugin.
Why was it changed?
* Addition of noConflict() @jQuery to prevent problems using Galleria
* in Wordpress (when using jQuery in Wordpress' core) and also to
* prevent potential problems when other JS libraries are being used,
* such as Prototype.

* @desc Convert images from a simple html
into a thumbnail gallery
* @author David Hellsing
* @version 1.0
*
* @name Galleria
* @type jQuery
*
* @cat plugins/Media
*
* @example $('ul.gallery').galleria({options});
* @desc Create a a gallery from an unordered list of images with thumbnails
* @options
* insert: (selector string) by default, Galleria will create a container div before your ul that holds the image.
* You can, however, specify a selector where the image will be placed instead (f.ex '#main_img')
* onImage: (function) a function that gets fired when the image is displayed and brings the jQuery image object.
* You can use it to add click functionality and effects.
* f.ex onImage(image) { image.css('display','none').fadeIn(); } will fadeIn each image that is displayed
* onThumb: (function) a function that gets fired when the thumbnail is displayed and brings the jQuery thumb object.
* Works the same as onImage except it targets the thumbnail after it's loaded.
