integration with facebook

Hi, there is something i dont quite understand yet..

When i link the article on facebook, i get the post featured image with a ¨play¨ button (because of the video contained in the article), once you click on it nothing happens.

I want to have my normal featured image which users can click to see it expanded and tag themselves.

Thank you…
