Not sure of the detail, but there in lies the issue. It is not built yet, will require multiple devs to agree and implement, will take time and money, etc. It is ideal, but not ready, yet.
Of all the media uploaders I mentioned and out there, NONE of them do anything like this, because it’s hard!

In the meantime our nostr centralized media uploaders (nostr.build, void.cat, nostrimg.com, nostrcheck.me, satellite.earth/cdn) are fine for basic memes and photos. We are strongly advocating people not add anything too personal or sensitive and to use their own servers for that.

nostr:npub12262qa4uhw7u8gdwlgmntqtv7aye8vdcmvszkqwgs0zchel6mz7s6cgrkj , I agree an awesome decentralized media uploader and repository is needed for Nostr, but we need something until it’s built 🤙
