I would love to show the many bright faces reading and otherwise enjoying my library, but for their protection and by law, I cannot use their photos here.
Luckily there are many places to find images that have been licensed for the Creative Commons: in other words for anyone to use with various restrictions.
Any time photos are taken from the Internet, for personal, professional or student projects, care should be taken to comply with the photographer’s copyright. Many prefer to protect their images from use, but some share freely. You can learn about different licenses here.
