How to add an image in Tkinter?

There is no "Syntax Error" in the code above - it either ocurred in some other line (the above is not all of your code, as there are no imports, neither the declaration of your path variable) or you got some other error type.

The example above worked fine for me, testing on the interactive interpreter.

Python 3.3.1 [MSC v.1600 32 bit (Intel)] on win32 14.May.2013

This worked for me, by following the code above

from tkinter import *
from PIL import ImageTk, Image
import os

root = Tk()
img = ImageTk.PhotoImage(Image.open("True1.gif"))
panel = Label(root, image = img)
panel.pack(side = "bottom", fill = "both", expand = "yes")
root.mainloop()
