//** Featured Content Slider script- (c) Dynamic Drive DHTML code library: http://www.dynamicdrive.com. //** May 2nd, 08'- Script rewritten and updated to 2.0. //** June 12th, 08'- Script updated to v 2.3, which adds the following features: //1) Changed behavior of script to actually collapse the previous content when the active one is shown, instead of just tucking it underneath the later. //2) Added setting to reveal a content either via "click" or "mouseover" of pagination links (default is former). //3) Added public function for jumping to a particular slide within a Featured Content instance using an arbitrary link, for example. //** July 11th, 08'- Script updated to v 2.4: //1) Added ability to select a particular slide when the page first loads using a URL parameter (ie: mypage.htm?myslider=4 to select 4th slide in "myslider") //2) Fixed bug where the first slide disappears when the mouse clicks or mouses over it when page first loads. var featuredcontentslider={ //3 variables below you can customize if desired: ajaxloadingmsg: '<div style="margin: 20px 0 0 20px"><img src="loading.gif" /> Fetching slider Contents.
