Display .png image with Tkinter and PIL

Question

I try to display .png file in Tkinter Label, but in effect I get just empty space in place where image should be displayed. It's very simple code and i have no idea what is wrong.

from Tkinter import *
from PIL import Image, ImageTk

root = Tk()

image = Image.open('image.png')
display = ImageTk.PhotoImage(Image.open(image))

label = Label(root, image=display)
label.pack()

root.mainloop()

Answer 1

You're calling Image.open() twice. It's enough to call it once. Use:

display = ImageTk.PhotoImage(image)

instead of:

display = ImageTk.PhotoImage(Image.open(image))

Answer 2

I managed to resolve this problem in this way:

image = Image.open('image.png').convert("RGB")

I'm not sure if it's correct, but it works.
