Python Tkinter Background image

[xavizara]

below is my code of a simple program where you can control a circle with buttons WASD. my question is, how do I add a background image? Please help me. :)

from Tkinter import *
import time, math, random

def timerFired(previousTime):
	currentTime = time.time()
	dt = currentTime - previousTime
	canvasWidth = int(canvas.cget("width"))
	canvas.after(40, timerFired, currentTime)
	redrawAll()
def key(event):
	if event.char == "a":
		for i in range(len(canvas.data.x)):
			canvas.data.x[i] = canvas.data.x[i] - 5
	elif event.char == "d":
		for i in range(len(canvas.data.x)):
			canvas.data.x[i] = canvas.data.x[i] + 5
	elif event.char == "w":
		for i in range(len(canvas.data.x)):
			canvas.data.y[i] = canvas.data.y[i] - 5
	elif event.char == "s":
		for i in range(len(canvas.data.x)):
			canvas.data.y[i] = canvas.data.y[i] + 5
	redrawAll()

def drawBackground():
	pass

def redrawAll():
	canvas.delete(ALL)
	drawBackground()
	canvas.create_text(int(canvas.cget("width")) - 10,
					   int(canvas.cget("height")) - 10,
					   anchor=SE,
					   text = "X = " + str(canvas.data.x) + " Y = " + str(canvas.data.y))
	for i in range(len(canvas.data.x)):
		canvas.create_oval(canvas.data.x[i] - canvas.data.r[i],
						   canvas.data.y[i] + canvas.data.r[i],
						   canvas.data.x[i] + canvas.data.r[i],
						   canvas.data.y[i] - canvas.data.r[i],
						   fill=canvas.data.color[i])
	
def init():
	canvas.data.groundHeight = 600
	canvas.data.x = [400]
	canvas.data.y = [300]
	canvas.data.r = [100]
	canvas.data.color = [""]
	canvas.data.backupX = []
	canvas.data.backupY = []
	canvas.data.backupR = []
	canvas.data.backupColor = []

def run():
	global canvas
	root = Tk()
	canvas = Canvas(root, width=800, height=600, bg="yellow")
	canvas.pack()
	root.canvas = canvas.canvas = canvas
	class MyModel: pass
	canvas.data = MyModel()
	init()
	root.bind("<Key>", key)
	timerFired(time.time())
	root.mainloop()

run()

You use canvas.create_i mage(x, y, image=name, + other options) see here for the create_image options. The "image=" must be a BitmapImage or PhotoImage instance.
