You may want to check out this thread in Profiles & Graphics Discussion:
It links to various threads that are useful for editing profiles and includes the profile coding tutorial, basic codes to help, etc. So yes, it absolutely does have what you need to add your image as your profile background. :) That said, it looks like someone already gave you the code. But in the future, the sticky I linked will be able to steer you in the right direction for profile coding help.
