Sometimes you can never underestimate the stupidity of users
I got a report from a user that they tried to put a URL into the Upload photo text box and when they submitted the ad their computer locked up. Now we all know that you ain't suppose to do that. Figuring that I had PPC 2.0 in test mode for less then one day and someone did it, others will do it too.
Maybe there should be some type of error checking done in the Upload fields.
