this is a small angular.js directive to inject a gravatar image into your HTML see examples below
download the package and link it to you index.html in a <script></script>
tag and then inject ngGravatar
into your module/controller/whatever
then wherever you want the gravatar simply use the <ng-gravatar></ng-gravatar
tag like so
<ng-gravatar hash="769a81e0ebf1c28cd80624ce79847b6ae59a20cd" size="500"></ng-gravatar>
this will render my current gravatar image with size of 500x500 (NOTE: the image size defaults to 300x300 if not set in the size attr)
