Using Python, Tkinter, canvas ,and photoimage function with some threading

My webhost not allowing some file extension so need to put image as individually (sorry)

The images are for operator sequence , I tried to put them all in a zip but not allowed.

Code (will also need the image files)

Download for operator images

Unzip the images of the operator to a folder and make sure to update the folder path in the python code.

I used spyder python ide if you forget to make the folder correct you may have to close the ipython console , fix the path and try again. Something in the PhotoImage in tkinter does not clean up correct when there is a python error. So i have to close the console part in the ide fix and rerun.
