Replace Gravatar avatars with static images
Created by: Gitoffthelawn
Avatars served by gravatar behave, in some ways, similar to a CDN. At the least, gravatar poses many of the same issues as a traditional CDN.
Some websites like bitbucket.org don't look great when the user simply blocks access to gravatar.com.
Would it be reasonable for this extension to have an option to replace "gravatars" with a static image?
