Altering your Google account profile image can assist with name acknowledgment so that moms and dads start to put a confront with a name as soon as they start getting emails from you. They wont have to wait up until the very first parent-teacher conference or open home night to make the association between your face and name.
If you have more than one instructor in your district with the same name or similar names (at one point there were three Mr. Burns and a Mr. Byrne in my district) students seeing an email with your profile picture can visually verify that they are emailing the correct individual.

how to change your Google profile image.
