	//Here's an example of how you can use the fetch function to fetch an NFT from Pinata:

	//In this example, the NFTImage component takes an nftHash prop that represents the hash of the NFT on Pinata.
	//The component uses the useState and useEffect hooks to fetch the NFT image from Pinata using the fetch function.
	// If the HTTP response is successful, the component sets the image URL in state using the setImageUrl function,
	// and renders an img element with the src attribute set to the image URL.
	//If the image URL is not available yet, the component displays a "Loading NFT..." message.
