You can change the height and width of the shape (as well as other general settings) in the General settings tab.
If your school photographer has entered your school’s colors into your school profile, clicking ‘Primary Color’ or ‘Secondary Color’ will change the shape to that color.
Adjusting the Radius of the shape smooths the edges. Setting the Radius to 100% turns the shape into a circle or oval (depending on shape dimensions.)
Be sure to save your changes when you are finished.
