How do you complete the yearbook in Bully Scholarship Edition?

Take pictures of all the students at the School with your camera to complete the yearbook and unlock the black ninja costume. there are only two people you dont need to worry about. you dont need to worry about Gary and Pete. once you complete the story mode their pics are automaticly placed in there. the best way to get the pics is to pull the fire alarm in the boys dorm then go to the exit and take pics. then go to each area. the library. the football feild. the library etc. enjoy
