The ImageTk module integrates PIL with Tkinter:
http://effbot.org/imagingbook/imagetk.htm

Here is a simple image viewer library, just call showImage() with your
loaded Image object:

# an image viewer
import ImageTk
from Tkinter import Tk, Label

class UI(Label):

    def __init__(self, master, im):

        if im.mode == "1":
            # bitmap image
            self.image = ImageTk.BitmapImage(im, foreground="white")
            Label.__init__(self, master, image=self.image, bg="black", bd=0)

        else:
            # photo image
            self.image = ImageTk.PhotoImage(im)
            Label.__init__(self, master, image=self.image, bd=0)

def showImage(im):
    root = Tk()

    UI(root, im).pack()

    root.mainloop()
