Modify Png and Json

Hi guys!

I have a question, I’m creating my first NFTs collection and I wanted to know something:
Can I edit my pngs on Photshop ( Ive troubles with some layers x) ) and my jsons right after I created my 7k build? Is there any consequences on my collection? Because I can see “Hash” and “Time” on Json so it’s maybe link to my pngs and IPFS could see a cheat or a fake collection?

Thank you and sorry if it sounds stupid!

If you edit your files and reupload them to IPFS, the hashes will be different.

Hashes are cryptographic computation done on your files, it’s a fingerprint, if you change any bit in the file, it will have a different hash.
