title: Supply an image thumbnail with my RSS feed
body: <p>I want the images in my RSS feed to be displayed so that if the feed is taken into Facebook my page will show the image with it.</p>
  
  <p>This is my RSS feed: </p>
  
  <pre><code>&lt;item&gt;
  &lt;title&gt;Title&lt;/title&gt;
  &lt;link&gt;www.website.com&lt;/link&gt;
  &lt;guid&gt;www.website.com/1/&lt;/guid&gt;
  &lt;description&gt;Description&lt;/description&gt;
  &lt;/item&gt;
  </code></pre>
  
  <p>Do I add <code>&lt;image&gt;&lt;/image&gt;</code> and just stick the URL in? Or should I use <code>&lt;media:thumbnail&gt;</code>? </p>
  
  <p>I don't want the image to be the main content but instead have it show as thumbnail preview like when sharing a webpage on Facebook.</p>
