When you post something on facebook:
When you hit the "add" button to add the link to the post, it moves it to a screen that shows a description of the link and a thumbnail. The thumbnail will have two little arrow keys directly to the right of it - if there's a choice of thumbnails with the link because there are many pictures or avatars, you should be able to click through to the one you prefer before you hit the "post" button.
