RECOMENDATION: pay attention to your students privacy!
Some of ours publications have students photos and we have to be carefull about it.
Make sure you have their parent's authorizations. I saw many children's photos and videos and it might be a problem. Personnally I never publish photos of my children/students.
I reminde you, that each teacher is responsible for their own publications!
May I suggest an adress to blur faces on videos. I think it's very usefull.
