Changing user avatars
When a new user registers on a website, the system assigns to them a default avatar. Later, the user can change their avatar on a page containing the My account web part, on the Personal settings tab.
Here, the system allows users to delete their avatar, upload a new one, or select a predefined avatar.
Changing user avatars in the administration interface
Users with access to the administration interface can change their avatars in the My profile or Users applications.
