Some things need to be clarified here: where were the pictures produced (which program output them as GIF), and how are they being transferred. There are no "GIF variants"; that's like saying "SCSI variant" (oops, maybe not). Anyway, it's possible that some special header is being added; I'd guess 128 bytes. Try BLOADing a picture at about $2000 and see if the GIF87a header shows up at about $2080... GIF *is* GIF *is* GIF; while there might be some additional headers/footers, any change to the format of the stored image would render it non-GIFian. > -- Frank Malczewski -- fadden@cory.berkeley.edu (Andy McFadden) ...!ucbvax!cory!fadden labc-3dc@widow.berkeley.edu Just send the darn letter and let the computer figure it out.
