Service
Gravatar was revived - in the form of version 2.0.
Gravatar is a service for storing avatars. The user can "bind" your email to a specific avatar; all sites that support Gravatar will display this particular avatar. Thus, the service can be called a centralized repository of user avatars (just like OpenID, for example, can be called a “centralized identifier”).
In the free version, the user can specify one email and link two avatars to it. In the paid version, an unlimited number of email addresses per account and unlimited number of avatars are available for them.
