Can't seem to find the answer to this anywhere...

I would like to have additional Large images without having additional thumbnails, a pop window that will scroll through all of the large images available for the product. At the moment, I am handcoding a pop-up window for each product but it is getting tiresome! Any way to use the beautiful features of zen to do this automatically? To see an idea of what I want visit http://www.remnantclothing.com/index...products_id=80
and click "Additional Photos" in the description.

Thanks!
