When your school issues you a Google Workspaces for Education account your profile picture will just be an easy letter icon featuring your initials. Many individuals leave it that way only due to the fact that they do not understand how simple it is to alter it. In the video below I demonstrate
how to change your Google profile image.

On a related note, a great deal of individuals do not recognize that there is a distinction between signing into a Chrome profile and signing into a Google account. I discussed the difference in

Applications for Education
Altering your Google account profile image can help with name recognition so that parents begin to put a face with a name as quickly as they start getting e-mails from you. They wont need to wait till the first parent-teacher conference or open home night to make the association in between your face and name.
If you have more than one teacher in your district with the same name or comparable names (at one point there were three Mr. Burns and a Mr. Byrne in my district) students seeing an e-mail with your profile picture can aesthetically verify that they are emailing the appropriate person.
