Tkinter.PhotoImage question

[Dr. Kent L. Miller]

I would like to display image files onto labels and canvasses.  I noticed
however, that if I call PhotoImage from within a function, no image will
appear.  When I run the following code, a photo appears on the label but
not the canvas, even though the lines and bitmap do appear.  Is this a
Tkinter bug?  Is there a workaround?

import Tkinter

def body(master):
	f = Tkinter.Frame(root)
	f.pack()
	c = Tkinter.Canvas(f)
	c.pack()
	photo2 = Tkinter.PhotoImage(file="lena.gif")
	c.create_line(0,150,150,0)
	c.create_image(10,10,anchor=Tkinter.NW, image=photo2)
	c.create_line(0,0,150,150)
	c.create_bitmap(100,100,bitmap="info",foreground="gold")
	l = Tkinter.Label(f, image=photo)
	l.pack()

root = Tkinter.Tk()
photo = Tkinter.PhotoImage(file="lena.gif")
body(root)
root.mainloop()


Sincerely Yours,
