title: Google Static Maps rejects requests for some domains
body: <p>On some domains Google Maps returns instead of image this error message: The Google Maps Platform server rejected your request. You must use an API key to authenticate each request to Google Maps Platform APIs. For additional information, please refer to <a href="http://g.co/dev/maps-no-account" rel="nofollow noreferrer">http://g.co/dev/maps-no-account</a></p>
  
  <p>Domains where it does not work:</p>
  
  <ul>
  <li><a href="http://en.aston-martin-club.com/test_mapa.php" rel="nofollow noreferrer">http://en.aston-martin-club.com/test_mapa.php</a></li>
  <li><a href="http://en.ktm-club.cz/test_mapa.php" rel="nofollow noreferrer">http://en.ktm-club.cz/test_mapa.php</a></li>
  </ul>
  
  <p>Domains where it works:</p>
  
  <ul>
  <li><a href="http://en.renault-club.cz/test_mapa.php" rel="nofollow noreferrer">http://en.renault-club.cz/test_mapa.php</a></li>
  <li><a href="http://en.lada-club.eu/test_mapa.php" rel="nofollow noreferrer">http://en.lada-club.eu/test_mapa.php</a></li>
  </ul>
  
  <p>The image I display on web is from <a href="http://maps.googleapis.com/maps/api/staticmap" rel="nofollow noreferrer">http://maps.googleapis.com/maps/api/staticmap</a> URL. It is Google Maps Stati API <a href="https://developers.google.com/maps/documentation/maps-static/intro" rel="nofollow noreferrer">https://developers.google.com/maps/documentation/maps-static/intro</a></p>
  
  <p>Why on some domains it works and some not? If it wil not work for any domain, then I think I need to add "key=YOUR_API_KEY" parameter.</p>
  
  <p>I spent many hours trying to find out the reason, but did not succeeded. Any help is very welcome.</p>
