Is it obligatory to obliterate pictures in school notebooks, and is there a similar fatwa by Ibn Uthaymeen that does not command the obliteration of pictures in children's books?

The face of a picture that is in the form of a human or animal must be effaced. There is no harm in pictures of trees, stones, mountains, the sun, the moon, stars, and the like, and they do not need to be effaced. As for pictures of only the eye and the face, there is no harm in them. If the pictures in school textbooks are for the benefit of education, then there is no harm in them and they do not need to be effaced due to the hardship.
