Facebook, how to share a link thats just an image,

This Facebook post http://ift.tt/1OZW8aN looks like a photo post but is actually link, it clicks through to an external site.

I have tried sharing a link, removing all og metatags from my site except image path but it doesn't look like that.

The closest I can get is the default link behaviour without any title description, so just an image with the url besides/below rather than displayed over the top of the bottom of the image.

So what sort of post is this?

Thanks for any help.
