Abrir imágenes? Pitón

Estoy creando un juego de labryinth basado en texto, pero pensé que necesitaba algunas imágenes para ilustrar lo que está pasando. Por alguna razón, simplemente muere cuando bash ir a a2 (donde debería aparecer la imagen). Soy un principiante, así que no juzgues tanto mi código ^^

import Image a1 = ("a1 Go to the start of the Labyrinth", "You're at the start of the labyrinth") #Start a2 = ("a2 Go Left", "You've chosen to go left, unfortunatly it leads to nothing.") #Fail route a3 = ("a3 Go Right", "You've chosen to go right.") #Right route a4 = ("a4 Go Left", "You've chosen to go left") #Fail route a5 = ("a5 Go Right", "You've chosen to go right") #Right route a6 = ("a6 Go Right", "You've chosen to go right") #Fail route; end a7 = ("a7 Go Left", "You've chosen to go left") #Fail route a8 = ("a8 Go Left", "You've chosen to go left") #Fail route; end a9 = ("a9 Go Right", "You've chosen to go right") #Fail route; end a10 = ("a10 Go Forwards", "You've chosen to go forwards") #Right route a11 = ("a11 Go left", "You've chosen to go left; Congratulations, you won! You may restart") #Right route; end; victory fail = ("fail End game", "You lost!") #End game b1 = ("b1 Go Left", "You've chosen to go left") b2 = ("b2 Go Right", "You've chosen to go right") b3 = ("b3 Go Left", "You've chosen to go left") transitions = { a1: (a2, a3), a2: (fail, a1), a3: (b1,), b1: (a4, a5,), a4: (b2,), b2: (a7, a6,), a5: (b3,), b3: (a9, a10,), a6: (fail, a1), a7: (a8,), a8: (fail, a1), a9: (fail, a1), a10: (a11,), a11: (a1,) } location = a1 while True: print location[1] print ("Here you can: ") for (i, t) in enumerate(transitions[location]): print i + 1, t[0] choice = int(raw_input("Choose one ")) location = transitions[location][choice - 1] if location == a2: Image.open(picture.jpg) Img.show

• Marcas de agua invisibles en imágenes
• Extraer objetos conectados de una imagen en Python
• No se puede mostrar una imagen en Tkinter
