Tinypic. I had one absolutely bizarre issue with it once. There was an image of an Arcanine and a Ninetails fighting against two Houndooms that I needed for my RP when Theron and Chris KO were in a tag team match against Cerberus. Chris saw a wolf and a fox fighting off two coyotes, while Theron saw four mythical canines which the pokemon were the image reps for. Anyway, due to some odd glitch that I never could figure out there was a brief moment when the image coding changed to where it displayed some girl taking a picture of herself in front of a mirror. I double checked the coding and it was accurate to the picture on tinypic, but in RP's and PM's it showed the girl. I had a chat with Yaz and Killjoy about it so they knew what the image was supposed to be. Then the glitch fixed itself in time for the RP to be read properly. Other than that little mishap, tinypic has worked extremely well for me for over 2 years.
