When adding a webpage to a social network site, thumbnails are automatically generated. However there are many cases where you would want more control over the thumbnail used. Since this module is already generating the thumbnail I would love for it to also set the necessary tag needed to be used by these social networks.

You would only need to add the following meta tag, obviously replacing the image with the generated thumbnail.
<link rel="image_src" href="http://www.yoursite.com/images/42440347.jpg" />

What do you think about this idea? Feedback is appreciated.
