Thumbnail Loop in Marketpress Products Page

http://highgrade.epkhosting.com/store/products/

I have 3 products I've created and at first the most recent product image upload seemed to repeat itself across all products.

Later on I started uploading photos to another post (just a regular post) and the most recent upload from that post is now being called by each product in marketpress.

Never seen anything like this before. Please advise,
