More About Gravatars
“Gravatar” is the commonly used short name for “Globally Available Avatars”. The Gravatar service is actually managed by a subsidiary of the same company behind WordPress. A user will create an account on the Gravatar service and upload one or more images to be used as their avatar. Then, any site [where the user uses the same email address] can contact the Gravatar service to retrieve the user’s avatar for display.
