When you log in, tap on the upper right corner and tap 'My Profile'
Tap 'EDIT PROFILE":
Here you can add your photo, bio which other Stage Door Pass users can see.

If you are a theatre artist, this bio is NOT the bio and photo that appears in the projects you are tagged in. This is the profile you will use as a theatre fan. To edit your artist profile, log into your Stage Door Network to manage that profile.
