Keep the person, face, hair, clothes, hands, and cake 100% unchanged. ONLY add a large white projector screen on the wall behind the person. The screen is blank/empty. Dark room, cinematic lighting. Do NOT change anything else.
Take the second image (child photo) and paste it onto the white projector screen from the first image. Keep the woman with cake completely unchanged. The child photo should fit inside the projector frame naturally, as if being projected.
