I know that this question has already been asked several times, but I still couldn't figure out the answer to my problem. I keep getting the same error and don't know how to solve it.

This is my code:

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

window = Tk()
i = Image.open(pathToImage) 
if os.path.isfile(pathToImage):

     print 'image exists'
else:   
     print 'image does not exits'

label=Label(window, image=i)
label.pack()
window.mainloop()

It says that the image exists at the indicated path, but I keep getting this error message:

Traceback (most recent call last):
  File "ImageTest.py", line 31, in <module>
    label=Label(window, image=i)
  File "C:\Users\username\Anaconda2\lib\lib-tk\Tkinter.py", line 2597, in __init__
Widget.__init__(self, master, 'label', cnf, kw)
  File "C:\Users\username\Anaconda2\lib\lib-tk\Tkinter.py", line 2096, in __init__
(widgetName, self._w) + extra + self._options(cnf))
_tkinter.TclError: image "<PIL.PngImagePlugin.PngImageFile image mode=RGBA size=640x480 at 0x36DF278>" doesn't exist

I could not figure out how to solve this problem. Any help would be appreciated!

You should use PhotoImage instance as image value. Also, you need to keep the reference of your image.

im = Image.open(pathToImage)
ph = ImageTk.PhotoImage(im)

label = Label(window, image=ph)
label.image=ph  #need to keep the reference of your image to avoid garbage collection

A quick hacky fix is to provide the PhotoImage with the correct master:

i = ImageTk.PhotoImage(pathToImage, master=window)

It seems to be an Anaconda - Spyder - Iphyton problem. Solution is here: _tkinter.TclError: image "pyimage" doesn't exist
