I want to add a logo and banner image on my nft collection. What I want to do is to add the logo and banner image when i deploy my contract so that no matter what the marketplace platform is I always get the image and banner image for my collection.Otherwise I have to add logo and banner image seperately on each marketplace platform i.e opensea, Larva Labs/CryptoPunks etc. enter image description here

Opensea provides a standard in the form of contractURI() which can be added to the contract, and provides default values to the NFT collection. Check out this article to know more. I think this can resolve your query.
