It is my signature gif, and I have also noticed that a lot of the other signature attachments on other ppl's are gone as well. I have gone to posts where I added attachments, and when I go to look at the attachments in another window, it shows as done, and there is nothing there~! It hasn't happened with everyone's sgnature attachments, and actually I have not checked all that many attachments of other ppl's to tell you about that aspect, but I know that they aren't working on mine... don;t know if this will help~ but is worth a try!
