Open Graph in posts loop page

Question

I have a loop where all the posts have their own like button, when i click it the facebook window appears but it does not show the right post thumbnail. I think this is normal because in a posts loop the thumbnails are multiple so the script can not figure which one goes where - on the contrary the like button works perfectly on my single post pages.

So my question: is it possible to have the facebook like button work correctly on a loop page so that it grabs the right post thumbnail even if there are, say 10 posts in that page?

Maybe i should have multiple Open Graph metas, a set for each post in the loop, but i guess this would just cause a mess, is there something that i can do?
