Changing group avatars
When a new group is created, the system assigns a default avatar to the group. After that, group administrators can change the group’s avatar using the Group profile web part.
Users can delete the avatar, uploada custom one, or select a predefined avatar.
You can find a live example of this on the Community starter site. Sign-in as a group administrator (e.g. Josh with blank password, he is the Australian travellers group admin) and click Groups in the main menu. You should see the Australian travellers group under the My groups section. Click it and then use the Manage the group link in the Shortcuts section on the right of the page.
Changing group avatars in Administration
Site administrators can change the avatar of any group. If you open the Groups application and edit some of the groups, you will see the group’s avatar in the Avatar section.
