Rotating Banners via JS

Would like to have the option on the lower main banner to have it rotate through the selection of banners placed there. Would help sites that reciprocate links ect; I know it changes when the page is changed but many people may only visit the main page and thus never see other banners which can be helpful in their search for what they are looking for. Have seen this running on other carts. It can be done with Javascript which at present CAN be added to the html_includes/define_mainpage.php. This causes overkill on the banner situation though.

If we could make it an option in future version it would be nice for many. Believe more people would probably use the zencart banners too along with their own. Probably be able to have the script separate and call it through the admin sidebox controls.:smartalec: Making it optional includes everyones choices for cart configuration as some will not want to use it.
Have a great day!
