Facebook button. Does it work correctly?

I do think that it should also initiate a posting to facebook!?!

Like pinterest, google plus and twitter.

If you want share, something else has to be done.

This was one way to do it, http://www.boonex.com/forums/topic/Pass-the-right-photo-video-thumbnail-to-Facebook.htm

you can implement any way you want.
