Motivated by our love to twitter and its analytics we have launched a tool to complement this plugin.  https://wordpress.org/plugins/ki-twitter-analytics/ 

Analytics now available

there are two type of twitter card: summary_large_image and summary

<meta name="twitter:card" content="summary_large_image" />
if you need change to large image, you need add below code to twitter.php manually, not in the admin panel:


function twitter_card_type( $card_type, $query_type, $object_id )
{
  return 'summary_large_image';
}
add_filter('twitter_card_type', 'twitter_card_type', 10, 3);
