Nuking nostr.build would be way more noticeable, it seems like the vast majority of images posted on nostr are hosted there.

I really wish IPFS or WebTorrent were more performant, would be a great way to decentralize image hosting so that users who have loaded the image can seed it to others who wish to load it. 

In the meantime, a stepping stone towards fully decentralized images on nostr could be if more clients + relays implemented NIP-95 to allow images to be directly sent to relays and distributed that way.
