CSV are simple text files used mainly to store tables (as in Microsoft Excel). Saving images as CSV means converting to grayscale and storing every pixel in a different cell of a table.
GIF images were created by Compuserve. They can used no more than 256 colors and a single color transparenty (no Alpha channel). Today are rare since they offer low quality and huge filesizes. GIF animations are still in use.
