Until such a court case happens you literally don't know how that will shake out. If the artist runs out of money and can't pay for their server and the image goes down what exactly do you expect the court to do? I suppose they could force the artist to hand over the image and domain ownership to you assuming they still have it in the first place. And then you could stand provide the artworks url yourself. But what if they no longer own the domain and it's now owned by an opportunistic squatter? The domain wasn't part of what you bought so the legality of forcing the squatter to provide you the domain isn't quite so clear cut. You still of course own the ledger entry asserting that your payed for the url but you have no legal recourse to ensure that the url stays up.
