What you’re buying when you purchase an NFT is a link to a website. That link shows the image. If the link ever breaks because the website goes down or out of business, it’s pretty worthless. I would have thought the implementation would be based on something more enduring like the actual content and not a link.
Storing a full JPEG on the blockchain would be way too expensive. It’s not a bulk data storage system.
There are alternatives like storing a hash of some sort
A hash still isn’t the file itself. I think that the ones that use ipfs even have a hash in the URL.
