>> I'm not into Voyager data, but if they're like the shuttle photos, then They're not--the data on the CD-ROMs (which is where the files on that ftp site come from) are losslessly compressed. The method is Huffman- coding pixel differences in the black-and-white images, and requires some real software to decode them. I do plan to get the C code from the PDS (it's only about two buildings away--I work at JPL) and get it working on the NeXT, but I make no promises on when I'll do it.
