If you look at it in firefox and IE it's different, or at least it is for me. The correct picture {the cub's face} shows up in IE but some pretentious little pic with a saying, that I don't even own shows up in FF. Why would this be?
I use FF as my primary browser and have never had this problem before. The image broke a few minutes before the wrong one started showing up. This is my icon on a forum I have over 20,000 posts on so yeah it's slightly important. At worst I can just re-upload it somewhere else but I'm afraid of this happening again.
