Before you convert to an ImageTk, you need to first create a toplevel
window:

import Image
import ImageTk
import Tkinter as tk

root = tk.Tk()
#put your code here

And that should work. You'll still have to add the widgets and what-nots so
you can present your image, but in order to create an image with ImageTk,
you need to have a toplevel window created.

That's what this is telling you

Traceback (most recent call last):

  File "<stdin>", line 1, in <module>

  File "C:\Python26\lib\site-packages\PIL\ImageTk.py", line 113, in __init__

    self.__photo = apply(Tkinter.PhotoImage, (), kw)

  File "C:\Python26\lib\lib-tk\Tkinter.py", line 3285, in __init__

    Image.__init__(self, 'photo', name, cnf, master, **kw)

  File "C:\Python26\lib\lib-tk\Tkinter.py", line 3226, in __init__

    raise RuntimeError, 'Too early to create image'

RuntimeError: Too early to create image
