For a template to be compatable with auctiva it only requires a [DESCRIPTION_AND_IMAGES] tag in the HTML where the specific item's description and images will be placed. If you want to place each image individually you can use [DESCRIPTION] and then [IMAGE1], [IMAGE2] etc. The auctiva scrolling gallery can be used with custom templates as well and you can even customize its location using the [STORE_WINDOW] tag.
