You misunderstand. The problem with the function is not that it doesn't 
exit, it's just that with

>     root.after(200, next_image)

it schedules itself to be reinvoked by tkinter after 200 seconds. If you 
want to limit that to 10 times instead of indefinitely you can introduce a 
counter:

n = 10
def next_image():
    global n

    myLabel.config(image=random.choice(monster_images))
    n -= 1
    if n > 0:
        root.after(200, next_image)
