Animate gif in tkinter

If you want to see an animated gif in tkinter use this script

import tkinter as tk
from PIL import Image, ImageTk
from itertools import count, cycle

class ImageLabel(tk.Label):
    """
    A Label that displays images, and plays them if they are gifs
    :im: A PIL Image instance or a string filename
    """
    def load(self, im):
        if isinstance(im, str):
            im = Image.open(im)
        frames = []

        try:
            for i in count(1):
                frames.append(ImageTk.PhotoImage(im.copy()))
                im.seek(i)
        except EOFError:
            pass
        self.frames = cycle(frames)

        try:
            self.delay = im.info['duration']
        except:
            self.delay = 100

        if len(frames) == 1:
            self.config(image=next(self.frames))
        else:
            self.next_frame()

    def unload(self):
        self.config(image=None)
        self.frames = None

    def next_frame(self):
        if self.frames:
            self.config(image=next(self.frames))
            self.after(self.delay, self.next_frame)

#demo :
root = tk.Tk()
lbl = ImageLabel(root)
lbl.pack()
lbl.load('tenor.gif')
root.mainloop()
