hello friends;

I'v used the tutorial (http://www.daniweb.com/software-development/python/code/216550/tkinter-to-put-a-gif-image-on-a-canvas-python) but now the animation of my .gif doesn't work. I have used much more .gifs (animated) to check if the one was broken but no animated .gif is working in my GUI.
Any idea how to fix this problem?

Kind regards;
