Here is the Flash 10 fix for Slide Show Pro in Joomla

Replace this code in the mod_easyssp.php file.

Old code:
var attributes = {}
swfobject.embedSWF("/slideshowpro.swf", "", "", "", "9.0.0", "/expressInstall.swf", flashvars, params, attributes);

New code:
var attributes = {}
swfobject.embedSWF("slideshowpro.swf", "", "", "", "9.0.0", "/expressInstall.swf", flashvars, params, attributes);
