Kind 20 images are like "high quality" (if you wish) images. Stuff you want to share and keep in a gallery. Screenshots are not something I want to keep and share in my gallery.

Yes... this makes much sense for business that relay on visual. I can't imagine having my woodworking photos in the Twitter like clients...but a gallery like Olas, that's great. The beauty of nostr for sure.
Perhaps clients like Amethyst, Nostur, Coracle, etc need to give users a way to filter their galleries (do they have galleries? I know Nostur does). It would be good to have an option to “view all” or “view high quality only” for instance.
I added it personally to ametyhst. It automatically adds Olas images, but you can also manually add regular images.
