I was shocked to discover after looking more closely that most of the popular NFTs do not contain the image hash in the blockchain token data, nor do they even contain the URL to the image! They simply contain an integer (the token ID).

The ERC721 interface only requires String GetTokenURL(int tokenId) be implemented!

Are there a limited number of NFTs, then? INT_MAX?
tokenId is a uint256, so there are at most 115792089237316195423570985008687907853269984665640564039457584007913129639935 NFTs per contract.
Comparable to the number of atoms in the observable universe.
