如何使用 Tkinter 在 GUI 中导入和显示图像列表？

Question

from tkinter import *
from PIL import Image, ImageTk
import glob, os

root = Tk()
root.geometry("800x600")

# Function to display image
def displayImg(img):
    image = Image.open(img)
    photo = ImageTk.PhotoImage(image)
    newPhoto_label = Label(image=photo)
    newPhoto_label.pack()

# gta_images = []
os.chdir("gta")
for file in glob.glob("*.jpg"):
    # gta_images.append(str(file))
    displayImg(file)
    print(file)

# print(gta_images)    

root.mainloop()

I am trying to load images from a folder called "gta" and then display those game logos on my app. Program has no error but I think its a logical error. I am new to Python I don't know maybe there is some scoping logic problem in my displayImg funcion.

Note: When a PhotoImage object is garbage-collected by Python (eg when you return from a function which stored an image in a local variable), the image is cleared even if it's being displayed by a Tkinter widget.

For more.

from tkinter import *
from PIL import Image, ImageTk
import glob, os

root = Tk()
root.geometry("800x600")
photos = []

def displayImg(img):
    image = Image.open(img)
    photo = ImageTk.PhotoImage(image)
    photos.append(photo)#keep references!
    newPhoto_label = Label(image=photo)
    newPhoto_label.pack()

for file in glob.glob("*.jpg"):
    displayImg(file)
    print(file)
   

root.mainloop()

Not sure if it will work but try using the path of the gta folder you are getting the images from, instead of its name simply - replace the name with the path.
