Photos in tweets


#1

When i paste the url of any Flickr page (e.g. http://www.flickr.com/photos/sgwphotography/6904289989/?f=hp) in my tweet, a photo preview is added with “view photo” option.
I never installed Flickr api or granted any access.
I want the same feature to work with my website. I have tried adding the same meta tags as flickr pages but twitter doesn’t show image preview.

I added following meta tags and og tags. Am I missing anything else?

<meta name="medium" content="image">
<link rel="image_src" href="image url">

It is currently not possible to have your third party service surface naturally on twitter.com

Any changes on that policy or still the same?
