the photograph of Jessica's mother

I always loved that scene where Jessica "interacts" with her late mother's photograph by bringing her tea set over to the dresser with the framed picture on it. My question is, does anyone know if that picture is of Rebecca Harrell (Jessica)'s real-life mom? Her face looks exactly like Jessica's, so it would make sense if they used a picture of her real mother as a prop for the movie...but I wasn't sure.
