It is generally not a crime for teachers to take pictures of students without infringing on their privacy or without the consent of their legal guardians; However, if the act of filming violates the privacy of students, or without the consent of students and their guardians, it may be suspected of breaking the law. In educational activities, teachers should respect the legitimate rights and interests of students, including the right to privacy and portrait. If teachers use students' photos without authorization, especially in public places or for commercial purposes, it may infringe on students' portrait rights and constitute an illegal act, and may bear corresponding legal responsibilities. Therefore, teachers should be cautious when taking pictures of students, and ensure that they abide by relevant laws and regulations and respect students' personal rights.

The legal boundary of teachers' behavior;

1. Privacy protection: According to the law, no one may illegally invade the privacy of others;

2. Use of portrait right: Without my consent, I shall not use other people's portraits for commercial purposes without authorization;

3. Educational institutions stipulate that teachers must abide by the relevant regulations and guiding principles of the school when taking pictures of students on campus;

4. Guardian's consent: When minors are involved, it is usually necessary to obtain the explicit consent of the guardian;

5. Limitation of educational purposes: Teachers should take pictures of students for proper educational purposes or record class activities.

To sum up, when taking pictures of students, teachers should abide by relevant laws and regulations, respect students' personal rights, and must not infringe students' privacy and portrait rights, which constitutes an illegal act.
