Adding Images (GIFs still add)

If you try to add a GIF image the error message works fine, but an empty record is still added to the images list.

Sorry for posting nitpicky things like this, tell me if it bugs you and I'll stop, heh.

Thanks a lot for everything you've been doing with the site!

I fixed the problem, thanks for posting, it's good to clear all the bugs, they often don't get reported.
