The smart contract can do a content addressable way of identifying the image, with e.g. IPFS, and then, while in practice there may be a server which is hosting it for people, if anyone has the image saved, they can (if they choose to) continue act as a host for the image of the original server stops being around.

Not, uh, that NFTs for images like this aren’t silly and largely pointless,

but at least for some of them, the “there’s a server hosting the image” isn’t that much of an issue (at least provided that the person who “owns it” keeps the file locally and backed up)
