I'm building a (quite advanced) photo-viewer. It all worked pretty well, until I added about 300 photos and tested it in InternetExplorer :-S

First all the thumbnails were loaded directly, which I've changed to load when necessary. I also made some major changes to the sliding-animation, but IE seems to get jammed before that. Could anyone find out where I've failed?
