A minor clarification about IPFS here:

The metadata in the NFT can (and in my opinion _should_) point to an ipfs:// style URL. The websites displaying the NFT would have to use some redirector, but the actual token would have a URL that anyone could host (known as "pinning") on the IPFS network.

and now we're seeing the problem that even with that - or if you go look at the redirector URL and go directly to the IPFS link yourself - the artwork is frequently not present anyway.

Remember that IPFS is functionally just BitTorrent with magnet: links. So if nobody's seeding the file ... it's not there any more. And it looks like a pile of literally the sites selling NFTs don't bother seeding the files they've sold, mere weeks later. Thread: https://twitter.com/jonty/status/1372169695277760519
