This is a very simple python program that uses QT to display images on a screen. It was mostly written by ChatGPT4 as I've never used QT before. The "frame" is set to 1920x1080 for a 1080p monitor.
This version uses pyside6 but it appears to work just fine with pyside2 or PyQt*. I did see a crash using PyQt6 when running images at speed = 0.
It uses two timers. One to show an image and the other to show the word "Paused" when paused.
See keypress for support keyboard commands.
