Please stick to established Python coding rules, you code is hard to read:

import Tkinter as tk
from PIL import Image, ImageTk

def show_image():
    """image object image1 created in main"""
    canvas.create_image(250, 250, image=image1)
    #canvas.update()

frame = tk.Frame()
frame.pack()

canvas = tk.Canvas(frame, bg='white', width=500, height=500)
canvas.pack()

button = tk.Button(frame, fg="blue", text="Insert Image",
    activebackground='red', font=('verdana', 10, 'bold'), command=show_image)
button.pack(padx=50, side="left")

# create the image object here, not in the function
imageFile = "map.png"
image1 = ImageTk.PhotoImage(Image.open(imageFile))

"""
# default is center the image
canvas.create_image(250, 250, image=image1)
canvas.update()
"""

frame.mainloop()
