If you want to use a custom avatar, you can set it up with the following steps.
- Pick out your avatar. This can be any photo you took with your phone, found online, or anywhere else. For a professional look, use a photo like those on ID badges or in the yearbook.
- Login to Google Classroom.
- Click on the icon in the upper-left corner that looks like three horizontal lines. A menu will slide out of the left side of the page.
- Click on "Settings" at the bottom of the panel.
- Click on "Change profile picture".
- Follow the on-screen steps for selecting your photo. If its on your phone, you might need to email it to yourself and then download it on the computer.
That is it. Once its set up, every classroom, announcement, assignment, and comment you make will have your avatar next to it.
