I would like to be able to sort the pics alphabetically in this jquery script, anybody know where to add this functionality?

 

/**
* 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

* @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')
*   history:  Boolean for setting the history object in action with enabled back button, bookmarking etc.
*   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.

Was there some problem with the server-side/php solution that was posted in your other thread concerning this?

[smordue]

No, that worked great, this is a different issue. Maybe it can be solved the same way?
