A lot of fics have been written based on the idea of dead people living on as wizarding portraits, but I don't think too much thought has been given to how they work.
Were Sir Cadogan and the Fat Lady real people? Are all the animated picture in Hogwarts based on real people and real scenes that looked exactly like that, or are some merely figments of some artist's imagination? Do wizarding portrait painters put their subject in a god light making them look better or perhaps younger than they do in reality? How realistic would a portrait have to be to work? What about modern art or caricatures. Would changing how you depict someone change how their picture acts?
A possibly story idea for this might be giving Lilly Evans an artistic talent. Young Harry might discover a stash of her works in the attic at some point. He would find sketches and doodles from a young girls hat gradually as she got older turned more sophisticated and eventually as she learned the necessary magic got animated. Harry talks with the subjects of the wizarding pictures and learns from them without realizing that the pictures were not always true to live.
Lilly took some artistic license when drawing the people around her. Harry grows up with limited but extremely skewed knowledge of the wizarding world. He is in for a surprise when he finally goes to Hogwarts and so is the wizarding world.
