I am sorry. I am really a newbie to the twitter cards.
But it seems the twitter cards are now shown correctly after I validated a post on https://dev.twitter.com/docs/cards/validation/validator.
What I meant was, how to show a summary as shown at my tweet: https://twitter.com/AngkasaLand/statuses/378491342587850752.
But I am still figuring out how to have a Summary Card with Large Image.
Thanks anyway
