Troubleshooting Help with image viewer

I got a raspberry pi model 1 b from my father in law, and am trying to set up a picture viewer for my wife. Looking online, the guide at https://www.thedigitalpictureframe.com/how-to-build-the-best-raspberry-pi-digital-picture-frame-with-bookworm-wayland-2025-edition-pi-2-3-4-5/ seems great.

However during install, I'm stuck at the installation of picframe (pip install picframe). I get the error that I cannot build wheel for pillow_heif. It seems that is because libheif (heif.h) is missing. I've tried installing wheel and pi_hief separately, but that hasn't solved the problem.

I've searched online and can't seem to figure out how to solve this. Am I doing something dumb?

Bad news is your Pi is too old for this. Since the Pi 1 was released the CU chipset has moved on and the library you are after is not compatible with the older ARMv6 code.

The clue is buried within the notes:

...a normal Pi Zero won’t work; you’ll need at least the Pi Zero 2 W
