title: Include/exclude images for Pinterest "Pin It" button
body: <p>each post in my website, contains a photo gallery. The gallery consists of thumbnail images which link to full-size images.
  I have also placed a PinIt button in my posts. The problem is that it catches thumbnail images for pining. </p>
  
  <p>Based on what I've found about this kind of issue, I ended up with the following code which should exclude thumbnails from pining, and include full-size images instead. None of these, is donw though...</p>
  
  <pre><code>&lt;a href="path_to_full_image" rel="lightbox[single_post]" pi:pinit:media="path_to_full_image"&gt;
       &lt;img src="path_to_thumbnail" width="200" height="130" nopin="nopin" /&gt;
  &lt;/a&gt;
  </code></pre>
  
  <p>Any suggestions?</p>
