title: Posting/retrieving photo-comments using Graph API
body: <p>When I use the Graph API to fetch a comment containing an image, the returned JSON contains no reference to it, e.g.</p>
  
  <pre><code>{
    "id": "10151452996201039_9302037", 
    "from": {
      "name": "Anton Raxacoricofallapatorius Dyudin", 
      "id": "1534947411"
    }, 
    "message": "", 
    "can_remove": true, 
    "created_time": "2013-06-20T06:47:41+0000", 
    "like_count": 0, 
    "user_likes": false
  }
  </code></pre>
  
  <p>I am likewise lost as to what POST field can be used to embed a picture when commenting.
  How can I achieve either of the above?</p>
