I need to put a slideshow into a form.

Each record on the form is of an item for sale. I may have 0 or 1 or 2 or more pictures of the item. Rather than have to place lots of pictures into the form, I want some sort of slideshow effect - i.e. if no pictures are available for that item, then show nothing, but one or more, show the first picture with a forward and backwards to show the other pictures.

Any ideas? I've earched for "slideshow" but no luck so far.
