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">
