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.
