Whenever I try to upload anything, I get a "can't upload the picture on the server"

Server has all permissions set to 777
All subdirectories are set to 777
All thumbnail directories are set to 777

My website is **broken link**

Anyone have any thougths as to why it is doing this?  I did try changing the one line of code, from the post http://forum.phpwebgallery.net/index.php?a...t=ST&f=5&t=1171
and that didn't help either.

Any help appreciated, and KUDOS on the most excellent program!
