I've been trying to upload an avatar (on Tom's Hardware) and have thus far been unsuccessful. I have tried .jpeg, .gif, and .bmp and none of them will upload. I just keep getting this error: "Sorry, invalid file type". It says they must be 85 x 85 pixils or smaller but it also says if it is bigger that it will auto-resize. It also says 20 max. for file weight; what does this mean? Is this why it would accept it, or is it because I should be using a different file extension?
