Your image needs to be hosted somewhere online...like Photobucket. Or you can make a post in the <a href="http://forums.eyesonff.com/showthread.php?t=77901">Signature Service</a> thread and ask someone to host it for you, but I see you have alread posted there so I will close this.
Then the image url needs to be inserted between the [IMG] tags into the signature field.
