title: Retrieve thumbnail URL from page properties in AEM 6.4 using sightly
body: <p>Is it possible to insert thumbnail image URL from page properties of Thumbnail tab into og:image inside meta tag. I am able to get values of pageTitle and description properties but not the image. Or is there a better way to handle this?</p>
  <pre><code>&lt;meta property=&quot;og:url&quot; content=&quot;${head.pagePath}&quot; /&gt;
  &lt;meta property=&quot;og:title&quot; content=&quot;${properties.pageTitle}&quot; /&gt;
  &lt;meta property=&quot;og:description&quot; content=&quot;${properties['jcr:description']}&quot; /&gt;
  &lt;meta property=&quot;og:image&quot; content=&quot;imageURL&quot; /&gt;
  </code></pre>
