ok well I'm working on making a dungeon explorer and I can't get images to work...so far I have this

from Tkinter import *

class App:

    def __init__(self, master):

        frame = Frame(master)
        frame.pack()

        canvas = Canvas(frame, width = 225, height = 225)
        canvas.pack()

        gif1 = PhotoImage(file = 'Fhall.gif')
        canvas.create_image(0, 0, image = gif1, anchor = NW)

root = Tk()

d = App(root)

root.geometry('225x225+0+0')
root.resizable(FALSE,FALSE)
root.wait_window()

python

Here it is working, the image must be saved from garbage collection by saving somewhere, here we save it as variable of the canvas instanse.

from Tkinter import *

myimage = 'Fhall.gif'

class App:

    def __init__(self, master):

        frame = Frame(master)
        gif1 = PhotoImage(file = myimage)

        canvas = Canvas(frame, width = 225, height = 225)
        canvas.create_image(0, 0, image = gif1, anchor = NW)
        canvas.image = gif1 ## save image from garbage collection!
        canvas.pack()
        frame.pack()
        master.geometry('225x225+0+0')
        master.resizable(FALSE,FALSE)
        master.wait_window()
        

root = App(Tk())

I think I may have messed something up but I don't know what...I created another file to execute to shorten the coding but here are the two files

from Tkinter import *
import operator
import view

info_dict = {}
info_dict["area"] = 1
fhall = 'Fhall.gif'
fwall = 'Fwall.gif'
frhall = 'FRhall.gif'
flhall = 'FLhall.gif'
frlhall = 'FRLhall.gif'
info_dict["direction"] = "north"
class App:

    def __init__(self, master):

        frame = Frame(master)
        frame.pack()

        def start():
            if info_dict["area"] == 14:
                pic = view.view(1,0,0,0,info_dict["direction"])
                wall = view.wall(1,0,0,0,info_dict["direction"])
            if info_dict["area"] == 12 or info_dict["area"] == 20:
                pic = view.view(1,1,0,0,info_dict["direction"])
                wall = view.wall(1,1,0,0,info_dict["direction"])
            if info_dict["area"] == 21 or info_dict["area"] == 24:

    return wall

I put some print statements so I know it's updating the picture but the image on the canvas isn't changing any help?
