title: Facebook OG:Image tag is not included in Opengraph in facebook debugger
body: <p>I have included the meta tags in the head section of the page</p>
  
  <pre><code>Og:url
  Og:image
  </code></pre>
  
  <p>like this:</p>
  
  <pre><code>&lt;title&gt;villas&lt;/title&gt;
     &lt;meta property="og:url" content="https://louverturetravels.com/h/villas/v/i/villas/store_systeme144.html?NxTy=110464" /&gt;
     &lt;meta property="og:image" content="http://louverturetravels.com/h/villas/dx577khz83dc.cloudfront.net/3330/280a471c-2661-4dd5-b8e5-6fc6876654fd.jpg" /&gt;
      &lt;meta property="og:image:secure_url" content="https://louverturetravels.com/h/villas/dx577khz83dc.cloudfront.net/3330/280a471c-2661-4dd5-b8e5-6fc6876654fd.jpg" /&gt;

    <p>In the debugger -scraped URL - See exactly what our scraper sees for
    your URL</p>
  </blockquote>
  
  <p>Now when I follow the scraped URL - I can clearly see the image tag.
  like this:</p>
  
  <pre><code>&lt;!-- The above 3 meta tags *must* come first in the head; any other head content must come *after* these tags --&gt;&lt;title&gt;villas&lt;/title&gt;
  &lt;meta property="og:url" content="https://louverturetravels.com/h/villas/v/i/villas/store_systeme144.html?NxTy=110464"&gt;
  &lt;meta property="og:image" content="http://louverturetravels.com/h/villas/dx577khz83dc.cloudfront.net/3330/280a471c-2661-4dd5-b8e5-6fc6876654fd.jpg"&gt;
  &lt;meta property="og:image:secure_url" content="https://louverturetravels.com/h/villas/dx577khz83dc.cloudfront.net/3330/280a471c-2661-4dd5-b8e5-6fc6876654fd.jpg"&gt;
  </code></pre>
  
  <p>Based on the raw tags, we constructed the following Open Graph properties.
  All properties like</p>
  
  <pre><code>OG:url
  OG:type
  OG:title
  OG:description
  </code></pre>
  
  <p>All are all correctly retrieved except
  <code>OG:image</code>.</p>
  
  <p>Am I missing anything?</p>
