Twitter cards: large image with summary doesn't show up

[FirePrometheus]

I have a website http://www.fireofprometheus.com
And my twitter is http://www.twitter.com/fireprometheus

My cards are validated (I have large image with summary), I use wordpress SEO YOAST, but if you check my twitter, none of my blogposts show up with an image and summary.

Can anyone help me and tell me what’s going on?

Actually it shows up fine:

When I click on summary I do see the image with a summary. But when I go to my profile page, I only see my tweet (without the i

mage and summary) just summary in the lower right corner, Is that normal?

[ePirat]

Yes, that is expected behavior.
