If you use your own avatar server to provide profile pictures for your users, you can use that instead of Gravatar for the default profile pictures. In order to do so, you need to add ``$cfg->remoteavatarbaseurl = 'http://example.com/avatar/';`` (with the correct URL to your service) to your config.php.
