You need to remember that ChatGPT and its friends are very good at
stitching stuff from the web together in such a way that it looks
like it was done by a human. But that's all. They make no promises
about the stuff being accurate or correct in any meaningful sense.

And as you may have discovered they are extremely poor at debugging.

Here is an almost minimal version that works. I did add a couple of
extras for usability and debugging's sake.
It's quite a bit different...

import os
import time
import tkinter as tk
from PIL import Image, ImageTk

# Get a list of all .jpg files in the folder
folder_path = "c:/Users/Tim Carr/Pictures/_Parents"
image_files = [f for f in os.listdir(folder_path)
                 if f.endswith((".jpg",".jpeg",".JPG",".JPEG"))]

index = 0

def show_image(interval=3000):
    global index, thePhoto, thePicture

    thePicture.destroy()
    del(thePhoto)

    # Display next image for 3 seconds
    if index < len(image_files):
       file_name = image_files[index]
       image_path = os.path.join(folder_path, file_name)
       caption['text'] = image_path

       # create and display a new image
       newImage = Image.open(image_path)
       thePhoto = ImageTk.PhotoImage(newImage)
       thePicture = tk.Label(window, image = thePhoto,
                             width=newImage.width)
       window['width'] = 500
       thePicture.pack()

       # get ready for the next update event
       window.after(interval, lambda t=interval: show_image(t))
       index += 1
    else:  # we're finished
        window.quit()


# Create a Tkinter window
window = tk.Tk()
window.title("Image Viewer")
caption = tk.Label(window, text=image_files[-1].lower())
caption.pack()

theImage = Image.open(os.path.join(folder_path,image_files[-1]))
thePhoto = ImageTk.PhotoImage(theImage)
thePicture = tk.Label(window, image = thePhoto)
thePicture.pack()

show_image()
window.mainloop()
