title: Facebook - How to change the image posted for comments on my app?
body: <p>I have an app with a comment box inside it, which I inserted as a social plugin</p>
  
  <pre><code>&lt;fb:comments href="https://apps.facebook.com/myappname"&gt;&lt;/fb:comments&gt;
  </code></pre>
  
  <p>When a user posts a comment using that comment box, Facebook does not show the correct image. With <a href="http://developers.facebook.com/tools/debug/" rel="nofollow">Facebook debug</a> I can check that the Open Graph tags for the page of my application use the application icon as image - which is what I had expected.</p>
  
  <p>Still, when a user uses this comment box, on his profile appears a random image from my app. Is there a way to fix this?</p>
