Pictures are stored in a different representation. Otherwise I could download the image, re encode using WebM, put it inside a zip file with other random files as well, and then there would be no single file with their copyrighted material. Because LLM keep their data on files. Unless we don't keep the data on files but on a Blob on a SQL database! Yay this is fun
