The error "pyimage1 doesn't exist" doesn't let me set background image

Question

I want to put the image for background.My code follows..

import PIL
from PIL import ImageTk
from PIL import Image
import PIL.Image
class App(tk.Tk):
  def __init__(self):
   
    
    super().__init__()
    self.withdraw()
    
    self.root1 = Tk()  
    self.root1.geometry('800x690')  
    self.root1.title('tkinter')
    img =PIL.Image.open('4.jpg')
    bg = ImageTk.PhotoImage(img)


   # Add image
    label = Label(self.root1, image=bg)
    label.place(x = 0,y = 0)

The error is: "_tkinter.TclError: image "pyimage1" doesn't exist". How can I set background image?

Answer 1

Another way is to remove super().__init__(), so you can use self.root1.

Add self.root1.mainloop()

snippet:

from PIL import ImageTk, Image
import tkinter as tk
 
class App(tk.Tk):
  def __init__(self):
    self.root1 = tk.Tk()  
    self.root1.geometry('800x690')  
    self.root1.title('tkinter')
     
    img =Image.open('4.jpg')
    bg = ImageTk.PhotoImage(img)

   # Add image
    label = tk.Label(self.root1, image=bg)
    label.place(x = 0,y = 0) 
    self.root1.mainloop()

App()

I think the problem comes from the chaotic way you create your App: you run super.__init__(), which already initializes self as a TK instance, so the root is actually the App() itself. Here is some cleaned-up code that worked for me (I cleaned up the messy imports too):

from PIL import ImageTk, Image
import tkinter as tk

class App(tk.Tk):
    def __init__(self):
        super().__init__()
        self.geometry('800x690')
        self.title('tkinter')
        img = Image.open('4.jpg')
        bg = ImageTk.PhotoImage(img)
        # Add image
        label = tk.Label(self, image=bg)
        label.place(x=0, y=0)

        self.mainloop()

a = App()
