Submitting Screenshot - Bug

I've been trying to upload two screenshots but they are not going through it seems. They meet most of the requirements set, and are not offensive in any way. When I hit the submit button, it sends me back to the main page with a different URL, as if the screenshot was sent. Currently using Mac OS X 10.4.11 and Safari 3.1.2.

EDIT: Tried using FireFox just now and it worked fine. Must be a problem with Safari.
