Since the metadata is attached to a Tx not to the NFT, and is unique per transaction, there can not be such a thing as a Batch minting of NFT with each one having different metadata for example "image", is it?

I need to mint like 10 000ks NFTs, so i think my NFTs will all share same, image, and all i can change is the name and policy for doing them unique NFTs. Am I right?

EDIT: In fact it is not possible even that they satisfy the 721-Standar https://cips.cardano.org/cips/cip25/, is it?

Yes, it's possible. You can mint multiple NFTs using different metadata, all this in the same transaction. Here is an example of how you should structure your metadata

Take a look on this: How to mint multiple NFT assets in the same transaction?

But you have the restriction of the max transaction size, you can't go over that limit. Depending of your metadata, you'll be able to mint 35-45 NFTs in the same transaction.

    Yes, because the image displayed is based on the token name and the token name is defined in your metadata.
