"We had some problems with TinyPic in the past and had to ban its usage on the site so TinyPic images will not work."
There was nothing up in terms of copyright ^^That certainly is a problem.
The issue with Tinypic is that it can and will recycle urls. This issue worsens when you realize the fact that Tinypic doesn't have a filter for any sort of NSFW/inappropriate/adult content. There have been instances in the past where someone's image was suddenly changed to something that has no place on the FH forum. It wasn't common, but it was enough of a concern for us to disallow Tinypic completely
