When you create your own account or add student accounts, by default the system randomly assigns you a profile picture. Here's how you can select a different profile image or upload your own.
1) Login to your Buncee account
2) Go to View Profile and Badges
3) On the profile page, click the pencil next to your picture
4) Select a different avatar or upload your own and click Save Changes!
Please note: This feature is not available on the iOS app. iOS users you can change the avatars by accessing the mobile site.
