I'd like to use the user
string property (which is the url of a user's avatar image e.g. http://www.gravatar.com/avatar/fbc10e7e541ba1f171a06af062bef7c0?s=128&d=identicon&r=PG) and wondered if there's any documentation about the dimensions of the avatars. I have searched both, Gravatar specs, and the stack exchange api documentation but can't find any reference.
profile_images on Gravatar? And are they all the same dimensions? The few I've looked at all seem to be 80 x 80.
