A mod for page thumbnail????

Hi pals,

I have an idea for some time about a mod that will add a tag on the content view page for video, photos, groups, etc etc.

The thumbnail for a specific post will be its page thumbnail. I have found many post about the problem when you share a post with facebook its thumbnail doesn't show up. This module is just about that and you membership settings will not effect it. So anybody interested in this kind of mod and most important is there already any mod for this otherwise it will be a time waste to work on it.

hmm!! i think i posted it in wrong place..

/me checks his compass.

Looks fine. 

for those who doesn't get the idea here is a screen shot

Here when you share a site its image is pulled up by facebook (if any) but this doesn't happened to contents and this is about that.
