Product thumbnails, on product pages, aren't working.

Example page:
http://www.longboardphysics.com/shop/fish-bamboo-2/

Wordpress 3.5.
Shopp 1.2.5

I've deactivated one plug-in at a time, refreshed the page, to see if there was a conflict. No luck.
I've activated twentytwelve and deactivated Atahualpa and the thumbnails work.

Ideas?

Thanks!

I don't know what it suppose to look like, so it looks fine to me. if it is incorrect you need to explain what is wrong.

I'm sorry. The thumbnails under the larger image aren't clickable. When you click a thumbnail, the larger images is suppose to change. It does not.

as you say, they are not links. But because that is a premimum plugin that I don't own, I can't look into it.
Have you contacted the plugin develpoer?

Yes, I have been working with support, at Shopp, who suggests since it is a theme conflict, I should work with the theme support staff or switch themes. The site is already completely custom built in Atahualpa, and I would lose a lot of time if I had to completely redo the site in a new theme - plus I would like to be able to use Atahualpa with Shopp for future sites. Suggestions? I have used Shopp with several other themes and have not run into this problem before. I have narrowed it down to a theme conflict, without a doubt, but I can't figure out WHAT the conflict is, or how to fix it.

without access to the plugin, I'm not sure what I can do to help you.
