title: Has Google pagespeed v5 removed screenshot support?
body: <p>Google Pagespeed v4 worked using "screenshot" to archive our newspaper website daily, until Wednesday this week. I can find no information if they removed support for 'field=screenshot' but it no longer returns JSON. Is there a new method to capture screenshot, or is it gone?</p>
  
  <pre><code>private function capture_thumbnail(){
          if(false === $data = file_get_contents('https://www.googleapis.com/pagespeedonline/v5/runPagespeed?url=' . $this-&gt;url . '&amp;filter_third_party_resources=true&amp;screenshot=true&amp;strategy=desktop&amp;fields=screenshot&amp;key=' . $this-&gt;google_server_api_key))
              throw new Exception('Could not get url contents');
          $data = json_decode($data, true);
          if(empty($data['screenshot']['data']))
              throw new Exception('Screenshot data empty');
          $image = str_replace(
              array('_', '-'),
              array('/', '+'),
              $data['screenshot']['data']
          );
          $dir = SCREENSHOTS_DIR . date(CAPTURE_DIR_DATE_FORMAT) . '/';
          if(false === file_exists($dir)){
              if(false === mkdir($dir))
                  throw new Exception('Could not create screenshot directory');
          }
          if(false === file_put_contents($dir . date('H') . '.jpg', base64_decode($image)))
