Display a folder of images very quickly

readme.md

Give this folders as arguments, and it will display all the images in those folders as quickly as possible, letting you skim through large collections of similar images, for instance.

image_movie.py

from tkinter import Tk, Label
from PIL import Image, ImageTk
import os
import sys

# Skip every n frames.  Use 1 to show all images
skip = 1

try:
    root = Tk()
    image = Image.new(mode='RGB', size=(640, 480))
    photo = ImageTk.PhotoImage(image)
    img = Label(root, image=photo)
    for folder in sys.argv[1:]:
        n = 0
        files = os.listdir(folder)
        for filename in files[::skip]:
            filename = folder + '/' + filename
            try:
                image = Image.open(filename)
            except IOError:
                continue
            n += 1
            photo = ImageTk.PhotoImage(image)
            img.configure(image=photo)
            img.pack()

            root.update()

        print('Displayed {} of {} files in {}'.format(n, len(files),
                                                      folder.split('\\')[-1]))

    root.mainloop()
except Exception as err:
    print(err)
    input()

Really neat and efficient!
