Praise be to Allah.
We put this question to Shaykh ‘Abd-Allah ibn Jibreen (may Allah preserve him) who replied as follows:
This action is obviously beneficial in terms of sharee’ah, and there is a need to use pictures to teach them, because descriptions alone may not be sufficient. Pictures in films are not lasting, so they do not come under the rulings that forbid taking pictures.
And Allah knows best.
