Adding images to CSV

Hi, so I want to create a claim page with anywhere from 50 to 125 NFTs. The NFTs are high quality art, 1/1’s, ERC-721. I have the CSV templet, but I don’t understand how to properly insert that many images into a single CSV. I don’t even know how to get the string data of my image. Wouldn’t each image be a massive wall of text?

Last time I manually uploaded 107 images, created individual claim pages for every single one. It took ages. I want to find a better way.
