WOOOooow I loved scribble puzzle. I soloved your problem and save pics too

while(True):

    ret, frame = cap.read()
    height, width, ch = frame.shape
    roi_height = int(height / n_rows)

    images = []
    for x in range(0, n_rows):

    for i, face in enumerate(images):

WOOOooow! I loved scribble puzzle. I solved your problem and save pics tootoo. I added some enumerate to save pic.

    images = []
    for x in range(0, n_rows):
