first of all you have to upload the picture to a host.
www.ehomebook.com is a good place. Then you take the url of that pic and put it in ur sig box in ur user cp. At the front of the url put [ img ] (without the spaces) and then at the end of ur put [ /img ] (again with no spaces)
it should look like this:
[ img ]linkgoeshere[ /img ] (no spaces between the bracket and img thing though)
