At first find some NFT conctract or Content Identifier (CID). Also you can create you own. For example we will use pinata.cloud
For register on pinata you need just email.
Confirm and let’s build.
Select Files tab, then click add files and upload file. Wait a minute while CID and other are generated.
After file uploaded click on CID to copy it.
Paste your CID in Content Address field on zkSync Web Wallet.
Authorize youself and Mint NFT. Pay fee around ~$0.20.
