  <p>I am working on putting the Facebook "Like" iframe on a site, and I am trying to follow the example found at <a href="http://developers.facebook.com/docs/reference/plugins/like" rel="noreferrer">http://developers.facebook.com/docs/reference/plugins/like</a>.</p>
  
  <p>I am putting in code similar to this:</p>
  
  <pre><code>&lt;meta property="og:image" content="http://ia.media-imdb.com/rock.jpg"/&gt;
  </code></pre>
  
  <p>But when I "Like" a page, it doesn't do anything with the image that I am aware of. Does anyone know what that data is supposed to do?</p>
