Show HN: PiSlide OS – the easiest way to display images on an RPi

I've always wanted an easy way to display images on a Raspberry Pi. No X11/wayland (just DRM), with modern image format support (JXL, HEIC/HEIF, AVIF, along with the standard JPG, PNG, BMP, TIFF, SVG), slideshow support, and easy to run.

I also figured it's a good way to use that old Raspberry Pi that's setting in a drawer somewhere, since I target the RPi 0-5.

I have some plans to add animated gifs, HW accelerated video, and a frontend for uploading photos/managing settings - but that's coming down the line!
