title: FB.UI Feed Dialog - cannot "share" a facebook's picture
body: <p>Sharing facebook photo (really a facebook photo) using mobile web app &amp; Feed Dialog. </p>
  
  <p><strong>The problem:</strong> <em>Cannot send facebook's photo to the Feed Dialog.</em></p>
  
  <p>All code works great. I get all properties as they sent to the function. </p>
  
  <pre><code>    FB.ui
          method: "feed"
          link: 'url'
          app_id: myAppID
          name: 'photo's name'
          description: ''
          caption: $('#albumName').text()
          picture: 'http://myUrl.com/logo.png'
  
      , (response) -&gt;
          if response and response.post_id
              console.log 'Photo was shared'
          else
              console.log 'Photo was not shared. Please try again'
  </code></pre>
  
  <p>If I place a <strong>static</strong> photo, to represent the <a href="https://developers.facebook.com/docs/reference/dialogs/feed/#params" rel="nofollow">Picture parameter</a>, all goes fine, <strong>But</strong> if I try to call <strong>a facebook picture</strong> I try to share, then I get a 500 server error.  </p>
  
  <blockquote>
    <p>GET
    <a href="https://www.facebook.com/dialog/feed?access_token=...662390597_s.jpg&amp;sdk=joey" rel="nofollow">https://www.facebook.com/dialog/feed?access_token=...662390597_s.jpg&amp;sdk=joey</a>
    500 (OK)</p>
  </blockquote>
  
  <p>This is totally bizarre. The URL that goes to the dialog iframe, goes with all the needed parameters, including access_token. </p>
  
  <p>It seems like a design issue. Like someone in facebook don't want us to pretend to be facebook when we customly share things using their feed dialog, when we share facebook photos.</p>
  
  <p>Am I right?</p>
