title: og:image doesn't work with Facebook
body: <p>Im including the open graph tag for a special Facebook image:</p>
  
  <pre><code>&lt;meta property="og:image" content="http://www.spaghetti-factory.ch/images/logo_sf_rosenhof_fb.jpg" /&gt;
  </code></pre>
  
  <p>But if you click the share-Link</p>
  
  <pre><code>&lt;a href="https://www.facebook.com/sharer/sharer.php?u=www.spaghetti-factory.ch" target="_blank" title="share on Facebook"&gt;..&lt;/a&gt;
  </code></pre>
  
  <p>it still shows the wrong image (it should show only the fox).
  See on the Website <a href="http://www.spaghetti-factory.ch" rel="nofollow">http://www.spaghetti-factory.ch</a></p>
  
  <p>Whats wrong? Thanks for help</p>
  
  <p>regards
