[Plugin: Feed Thumbnails] Not showing

Thanks for the Plugin –

I currently have one of my WP sites feeding a category on the dashboard of another using WP-o-Matic. The RSS comes thru – then trying to use your PI to get the thumbs to show as well.
Do you knoe if they are compatible?

here is the site.
