I want to publish a photography book within my school but don’t know what to do?

Strictly speaking, you must be publishing illegally by doing this.

But if you give it to your teachers, friends, classmates, etc. for free, without any ideas or content that should not be spread or promoted, and without infringing on the interests of others, this is considered "personalized printing". Just like DIY an annual calendar with your own photos.

Because it is in a small area and does not involve profit, it should not be illegal.
