ok, I know anyone can fix this issue by downloading Firefox (which is how I fixed it) but I thought I should let you all know that your game art uploader page will not work in IE7. (you just get the "Sorry, we only allow jpeg, gif, or png images" error) Anyway I thought you should be aware of this because according to this site, 21% of internet users use IE7 as their primary browser. (I'll leave whether they are stupid or not up to you)

i have IE6 and it wont let me upload pics

Good God, man. Why are you running that piece of shit? 

lol im using firefox now, and it lets me upload pics, so use firefox to upload pics

I still get the error message with Firefox, but the image appears anyways.

I downloaded Firefox today just to upload pics, it still failed and then alerted me that I had to install some flash add on, I did and now it works, IE7 does not get the add on request, there's the problem.
