Find the picture that you would like to use (for this I just found a picture on google to use that was an appropriate size as an example but this will work for any picture you would like to use as your signature), after finding the picture just right click and select "copy image url" (if using chrome) if not just right click and select "properties" and copy the link next to the section that says "address bar/URL"
