I remember reading older books were there would be a lot of pictures throughout the book. Hell even some modern ones have a lot of pictures in them. I was wondering how does that work? Does the Publisher decide or do you add it into your manuscript? Also when would you add it? Is there a general time where you put in a picture of the scene or what? I was thinking off adding art to my book (black and white obviously) preferably in a specific type of art form (kind of like the old Warhammer 40k books art. How it looks so wonky but nice).
