title: Facebook Share Dialog does not display thumbnails one first load
body: <p>I'm using the Facebook share dialog to share a specific url. The shared link contains an image which should be part of the sharing later on. The strange thing about this is that it works totally fine on mobile browsers. But desktop browser do not load the image at the first attempt. A simple reload of the sharing window fixes the missing image. Once this image shows up for at least one time it continues working in other browsers without additional reloads..</p>
  
  <p>So my question is: Does anybody knows why the first call of this url does not show images?</p>

  <p>Here is the output of the Facebook Debugger, which is free of errors and shows the image as well.</p>

  <p><strong>Update</strong></p>
  
  <p>Seems to work with the Feed Dialog without any issues. But this is another way of sharing which I would like to prevent since it requires an App ID.</p>
