Thanks Ryan.
I was able to implement this in seconds :), however it doesn't render properly with users with missing Gravatars. Gravatar api has built in default image options for this scenario. See (http://en.gravatar.com/site/implement/images).

To use these options, just pass one of the following keywords as the d= parameter to an image request: 404, identicon, monsterid, wavatar, retro, blank.
