I work as a designer for a department at a college. My main task is designing posters/flyers for student clubs to advertise their club meetings and events. I always try to use public domain photos from sites like Unsplash or Pixabay, but if the pictures have people in them do I need to obtain permission from the models, or does the use of images fall under non-profit/personal use?
I'm not too sure what my situation falls under because it's for school, but it's not necessarily educational (since these are student clubs). I also some times make flyers and brochures for the department itself.
