title: Can I stop the "this website does not supply identity information" message
body: <p>I have a site which is completely on https: and works well, but, some of the images served are from other sources e.g. ebay, or Amazon.</p>
  
  <p>This causes the browser to prompt a message: "<strong>this website does not supply identity information</strong>"</p>
  
  <p>How can I avoid this? The images must be served from elsewhere sometimes.</p>
