From your child’s profile page, tap the icon for the grade you wish to update. Tap the Class Photo link at the bottom of the screen. Choose a photo from your gallery or use your phone’s camera to snap a pic. Under each photo are optional fields to note the school year, school name and your child’s teacher.
PRO TIP: If you don’t have a class photo, you can upload any group photo of your child from that year or take a photo of the page of his yearbook. A landscape [aka horizontal] photo fits best.
