FWIW, the Picasa photo viewer was so nice that I installed an old version of Picasa on Linux via WINE just for the image viewer. It'll be great to have a native version.
Ah, that's sad. I miss the speed and intuitive UI/UX of the old Picasa. No image viewer has ever been able to handle massive photo libraries as well for me :(
I've been using it ever since on my windows machines because I've never found anything even coming close to it. I don't need anything feature rich with a 5 second startup time. I need something that's 500ms away.

This is just a vibe coded image viewer, nothing else https://i.imgur.com/uBxUj8d.jpeg
But Irfanview for Linux would be pretty sweet!
That said, I've been enjoying this trend of reviving software killed before its time! Someone recently did the same for Apple Aperture (RIP):
