Facebook AutoPost Image/Avatar Not Showing

Hi, my auto-post to Facebook is working great will all my EasyBlog posts except that there is no image/avatar that goes with the post.

There is a standard blank image that shows along with my post. I have created an image/avatar for the blogger and category. What controls the post image/avatar that gets shown on Facebook? Am I missing something in EasyBlog or is it in Facebook's control?

Thanks
Craig
