Demo_Animated_GIFs_Using_PIL.py

You'll find other animated GIF playback demos for PySimpleGUI that use the tkinter built-in GIF parser.

That is how the built-in PySimpleGUI Image.update_animation is used.

If you want to do the GIF file parsing yourself using PIL and update your Image element yourself, then

this is one possible technique.

This particular demo will loop playing the GIF file over and over. To not loop, remove the while True statement.
