Hehe, nice of you to add that now, but I dont think you need to. Is it in the Artisteer TOS that you need to link to them every time you do a website with the tool?

Can I resell or redistribute exported Wordpress™, Joomla!™, Drupal™ and Web Templates?
Yes, as long as you do not include Artisteer photo objects within your header (Header -> Foreground Photo), as those photos are licensed from a 3rd party only for your own use. You may re-distribute any other designs you create, including those with Artisteer header background photos (Header -> Background), glares, page backgrounds and other provided graphics, and your own photo objects.
