Randomize meta-data, picture and ID

Smart Contracts
1

Hi everyone, I'm sorry I'm new to this dev ... so need help or tutorials.
I need help, I want to randomize the metadata, image and ID on my NFT when I make it.

And I want the IDs to be unique and never reused, picture too.

I figured out how to use IPFS to store all data, but how do I create it randomly?

thx so much to help me

Depends on how the erc721 contract is written. Sometimes it's added in the constructor, sometimes there's a function to add it.
