title: Pictures in the like box missing
body: <p>I don't know if it's a temporary bug or a setting change but, as of today, the pictures I post on the page I manage are no more reproduced in the Like box (only the text is shown). 
  I get the same result when trying from the developers page: <a href="https://developers.facebook.com/docs/reference/plugins/like-box/" rel="nofollow">https://developers.facebook.com/docs/reference/plugins/like-box/</a></p>
  
  <p>Does any of you experience the same problem? For sure it's a hard blow to my like box visibility :-((</p>
