title: Post a picture fia Facebook API
body: <p>I'm trying to post a message with picture (from a public URL, not from my albums) to group's wall:</p>
  
  <pre><code>$response = $facebook-&gt;api("/$group_id/feed", "POST", array(
      'access_token=' =&gt; $access_token,
      'message' =&gt; 'This is a test message',
      'picture' =&gt; 'http://d24w6bsrhbeh9d.cloudfront.net/photo/agydwb6_460s.jpg',
      )
  );
  </code></pre>
  
  <p>Everything is fine, but I can't see a picture itself:</p>
  
  <p><img src="https://i.stack.imgur.com/kjgZt.jpg" alt="my post"></p>
  
  <p>What am I doing wrong? Thanks in advance!</p>
