This is maybe my third attempt at building this, and I'm gradually getting towards something that doesn't suck and have a bunch of 3rd party dependencies outside of Nostr. I'm kinda convinced there's a need for this, which is why I've stuck with it so long.
ZapGallery - a platform for photographers to upload their work to Blossom servers, and get paid in zaps, all managed via Nostr only. Sample deployment here: https://zap-gallery.vercel.app/
