  <p>Want to have share thumbnail when user shares site url using share button on site which uses <a href="http://www.facebook.com/sharer.php" rel="nofollow noreferrer">http://www.facebook.com/sharer.php</a> to achieve that.</p>
  
  <p>Site dose not have img tags, all images are defined in css.</p>
  
  <p>I added meta tags for image:</p>
  
  <pre>
  &lt;meta property="og:image" content="/images/branding/branding-logo.png"/&gt;
  </pre>
  
  <p>and</p>
  
  <pre>
  &lt;link rel="image_src" href="/images/branding/branding-logo.png"/&gt;
  </pre>
  
  <p>but it's not working :(</p>
