Script:Preload Image (with progress bar) Script
http://www.dynamicdrive.com/dynamicindex4/preloadimage.htm


I am having trouble with the preloading image script on Dynamic Drive, I followed the instructions, but when i visit the page with the script on it, it starts to load, but never completes, I am using IE7. If you could please look over the source code, and tell me where i went wrong, i would much appreciate it.
