jQuery domroll

/* jQuery domroll
   Modifies all image elements with a "domroll" class. Appends "_f2" to the source filename to create a roll-over image.
   Idea based on http://www.dynamicdrive.com/dynamicindex15/domroll.htm
   Requires jQuery and jQuery.Preload http://flesler.blogspot.com/2008/01/jquerypreload.html
*/

$(function(){
    $.preload('.domroll', {find:/\.([^\.]+)$/, replace:'_f2.$1'});
    $('.domroll').hover(function(){this.src = this.src.replace(/\.([^\.]+)$/,'_f2.$1');},function(){this.src = this.src.replace('_f2','');});
});
