When trying to upload my signature, i keep getting the message.. "Unable to determine Image Dimensions?"
You can't upload signatures so i'm guessing you mean your avatar. It's all fine so all i can think of is that you are uploading a strange file type?
It's sorted now. Not totally sure what the problem was but never mind. One thing to note however is could you please put the information in your current sig in one line if you want to keep it as having the current text and the image will make your sig far too large.
