thumbnail image in Facebook share shows only for the first post [closed]

Question

I realised that I have a strange problem when I try to share a post in facebook. From all my posts, only for the first post I created the thumbnail image shows for when I try to share the link in facebook, via a sharing plugin (i.e. shareThis, or sociable), or even when I directly paste the link in facebook myself. For the rest of posts I created I get no image at all. I should add here that thumbnail image shows ok when I share pages. The problem is only with posts.

I have build a child theme for twenty eleven, and when I removed it the problem was still there.

Then I removed twenty eleven and replaced it with Kubrick theme, and the problem was still there.

Has anyone ever a encountered a similar problem?

Apart from the thing that Facebook has been acting weird with thumbnails recently, you need to specify which image to use or else it will pick up a random one from the page.

I have coded a plugin for this, read its description and see if it helps http://wordpress.org/extend/plugins/facebook-like-thumbnail/

If you want to go with some custom code, I wrote a post a few months ago about how to control the Facebook thumbnail in WordPress.
