I would also like to do this.
With the new Facebook Open Graph stuff, you can define a thumbnail for that page in your <head> of the form
<meta property="og:image" content="[image url]"/>.
I would like to use
<meta property="og:image" content="<?php the_post_thumbnail(); ?>"/>
but since this is outside the loop, the tag returns nothing.
Is there a way to get this to work outside the loop?
Thanks
