choose which picture you want to use mate, then put the url in your signature box.
If its one from your computer use the "my picutre" link at the top of the page to put it on the sites storage system, if its on the net already right click on it scroll down to properties, click on that & copy n paste the url into your signature box.
Its easy when you get used to it.
