You have to have a photo already on the web somewhere, so it has a URL, like http:// petoftheday.com/ image/Pet.jpg - I put spaces in so it wouldn't work. type [ img ] -then your URL for your image -then [ /img ] under your signature in the place you edit that.

It can't have any spaces, just the image tags and the URL, and that should work! I had to put spaces in the middle of the img tags, just take those spaces out. Otherwise, it tried to post a nonexistent image!
