When i share a post from my blog in the facebook, the thumbnail is not showing up.
I don't no what to do. Somebody help me to solve this problem.
My blog is http://pronunciadodragao.blogspot.pt
Facebook doesn't work like the other AddThis buttons. Instead of accepting parameters that we pass it, Facebook requests the URL you're sharing and gets the data it displays from the meta and link tags in the header. To control how your page is shared on Facebook you should use OpenGraph tags which are described in Facebook's documentation here: http://developers.facebook.com/docs/opengraph/
You'll have to edit your Blogger template to add them.
