(function($) {
	$(function() {

			ss = $(".slideshow"),
			images = ss.find("li"),
			current = 0,
			length = images.length;
			delay = 3500;

		if ( length ) {
			queue();

		ss.hover(function() {
			clearTimeout( timeout );

		function advance() {
		        $(this).removeClass('shown');

			ss.prepend( images.eq( current ).addClass('shown') );
