ThingLink, the company that brought interactive images to Twitter last year, has turned its attention to Facebook after adding support for the world’s largest social network to its service.

Using ThingLink, Facebook users — and particularly brands — can now add images to Facebook Timelines that include embedded links, annotations, videos and, perhaps most interestingly, the option to share and purchase content. All of these additions are designed to make images — and ultimately brand messages — more shareable.

The company says that its support for Facebook will let users discover new content, and enjoy richer media and new brand experiences on the social network. For brands and advertisers, ThingLink is a chance to experiment with new, eye-catching and attention-grabbing materials.

ThingLink has more than 130,000 publisher partners, which include Armani, Nike and Adidas, and charges customers based on CPM, which is in the range of $5. The company was the first to introduce interactive images to Twitter, but rival Stipple beat it to the punch on Facebook.

Here is an example of how it could work using a interactive image from Microsoft. The image contains a linked video, outbound links — although none are active below since this is just a screenshot.

A more feature-rich demonstration comes via this image from Armani, which is also on Facebook:
