if master._last_child_ids is None: AttributeError: 'PhotoImage' object has no attribute '_last_child_ids'

Question

from tkinter import *
from PIL import ImageTk, Image

root = Tk()
root.title("Images")
root.iconbitmap(r"C:\Users\DellABD\Downloads\lolol.ico")


my_img1 = ImageTk.PhotoImage(Image.open(r"E:\imagespy\illusion.jpg"))
my_img2 = ImageTk.PhotoImage(Image.open(r"E:\imagespy\scan0053.jpg"))
my_img3 = ImageTk.PhotoImage(Image.open(r"E:\imagespy\scan0054.jpg"))
my_img4 = ImageTk.PhotoImage(Image.open(r"E:\imagespy\scan0055.jpg"))
my_img5 = ImageTk.PhotoImage(Image.open(r"E:\imagespy\scan0056.jpg"))

my_img_list = [my_img1, my_img2, my_img3, my_img4, my_img5]

my_label = Label(image = my_img1)
my_label.grid(row = 0, column = 0, columnspan = 3)


def forward(image_number):
    global my_label
    global back
    global forward

    my_label.grid_forget()
    my_label = Label(my_img_list[image_number - 1])

    my_label.grid(row = 0, column = 0, columnspan = 3)

def back():
    global my_label
    global back
    global forward

    global my_label
    global back
    global forward

    my_label.grid_forget()
    my_label = Label(my_img_list[image_number - 1])

    button_forward = Button(root, text = ">>>", command = lambda: image_number + 1)
    button_back = Button(root, text = "<<<", command = lambda: image_number - 1)

    if button_back == 1:
        button_back = Buuton(rrot, text = "<<<", state = DISABLED)

    button_back.grid(row = 1, column = 0)
    button_forward.grid(row = 1, column = 2)
    my_label.grid(row = 0, column = 0, columnspan = 3)



button_back = Button(root, text = "<<<", padx = 20, pady = 20, command = back)
button_forward = Button(root, text = ">>>", padx = 20, pady = 20, command = lambda: forward(2))
button_quit = Button(root, text = "Exit", padx = 20, pady = 20, command = root.quit)

button_back.grid(row = 1, column = 0)
button_forward.grid(row = 1, column = 2)
button_quit.grid(row = 1, column = 1)

root.mainloop()

when I run the programme and press the Forward button it shows me an error. I wanted to move on next image by pressing forward and when I press the first image disappears but next image dont show up and shows error.

Answer 1

The problem is this code:

Label(my_img_list[image_number - 1])

You are trying to use an image as the parent/master of a label. You need to use this instead:

Label(image=my_img_list[image_number - 1])
