All character avatars and banners have been reset in the registry. Much of the image code has been rewritten in order to be better optimized. As a result you will have to re-upload your character's avatars and banners. If for some strange reason you did not have a backup of your character images, please first check to see if they already exist in the media gallery. If you cannot find them for whatever reason, let me know. I have back ups of everything. :D
