Preview link before visiting

Take a look at Snap Preview Anywhere. Now you can preview link to see what it's look like before visiting. I found this feature useful.

But ... how do they do that ? :) I'm sure it's AJAX (without looking at the source). Adding some page element without page refresh from external resource is not new for me. I see that "cloud" is an png image about 7 Kb in size, and actually preview is also png image few kilobytes in size. The question is how to get a preview image. It is mystery for me :)

I don't think that it is something really new. But it is new for me.
