Tkinter: Window Not Showing Image

I am new to GUI programming and recently started working with tKinter. My problem is that the program won't show my image, I'm suspecing that it is my code that is wrong, however,

Solution 1:

try to change the image and check out if its still not showing up. if its still not showing up, try to change this line:

__DISPlAY__ = Image.open("Display.png")

to

__DISPlAY__ = Image.open("Display.png").resize((600,800))

see if it would show up now then change the width and height as you like.

Solution 2:

Pychamarm does not want to show the images, so to solve this problem i had to run the script from cmd every time...
