Card image is an archaic term for a character string, usually 80 characters in length, that was, or could be, contained on a single punched card. IBM cards were 80 characters in length, UNIVAC cards were 90 characters. A punched card typically held multiple data fields, some numeric, some alphabetic. Many data formats, such as the FITS image file format, still use card images as basic building blocks -- even though punched cards are now mostly obsolete.
Famous quotes containing the words card and/or image:

“He took the gold from them, formed it in a mold, and cast an image of a calf; and they said, “These are your gods, O Israel, who brought you up out of the land of Egypt!””
