Getting thumbnails to display on MarketPress

Multisite 3.1
Product Theme

I am trying to get thumbnails to display on the global store, sub sites store pages, and during the lengthy check out process so I can keep customers interested. Currently images only show on the product post page and elsewhere I just see the product label. How do I fix this?

I tried featured image and insert image through the upload/ insert image button on the Product Post... neither gives thumbnails...The global product widget thumbnail feature works but I want.
what am I missing?
