Due to a bug with IE 8 this code requires the following meta tag to force IE 7 compatibility mode. It works great in the rest of the browsers though (even the iPhone).
<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE7"/>More info about the bug can be found at the bottom of this page: http://labs.adobe.com/technologies/spry/ui/docs/image_slideshow.htm
