Question about harry potter?

The restricted section has books in it not meant for younger Hogwarts students ( so I guess there 'forbidden to younger students), they are meant for older students, like students in their 6th or 7th year at Hogwarts. I remember that somewhere in Harry Potter and the Philosopher's Stone when Harry, Ron, and Hermione were in their 1st year and they got the book they were looking for in the restricted section, there were these 'gory' images in the book.
