Embedding an Image in a Tkinter Canvas widget using PIL

I'm trying to embed an image in a Tkinter canvas using PIL, and for some reason it's not displaying. Any Ideas?

There are no errors or warnings. Just a blank Tk window.

My code:

import Tkinter
from PIL import ImageTk, Image


class image_manip(Tkinter.Tk):
    def __ini开发者_StackOverflowt__(self,parent):
        Tkinter.Tk.__init__(self,parent)

        self.ImbImage = Tkinter.Canvas(self)
        self.ImbImage.pack()

        i = ImageTk.PhotoImage(Image.open('test.png'))
        self.ImbImage.create_image(0, 0, image=i)

def run():
    image_manip(None).mainloop()
if __name__ == "__main__":
    run()

My guess is that the image is getting garbage-collected. Try saving a reference to "i" (eg: self.image=i)
