Where are The Beautiful Paintings images and NFT metadata stored?

The metadata, image, title, and rarity information for the digital artworks (NFTs) are stored on IPFS. IPFS is a distributed system for storing and accessing files, websites, applications, and data.  

The digital artwork (NFT) also contains the token ID, which has the input parameters used to create the visuals encoded into it and is used as the input to the generative algorithm. The generative algorithm is stored on the blockchain itself. This means that the artwork can be reproduced even if the image were not hosted on IPFS.
