This plugins shows Gravatar avatars instead of the generic user image.
Install the plugin on a Jenkins instance running at least v1.434. Thereafter, it will automatically show Gravatars for the users who have an email and a Gravatar. No extra configuration needed except installing the plugin.
The plugin will re-check every 30 minutes to see if any user has configured a Gravatar. Therefore, if you have configured a Gravatar and it does not show up, please wait at least 30 minutes before thinking it is a bug.
