- The files have a MacBinary header of 128 bytes which you will need to
- remove (or, re-upload from the Mac with the MacBinary option turned
- off). Actually, I think that VPIC will read past a MacBinary header, if
- present, which is an interesting feature.

- If you want to convert 24-bit to JFIF, then DO NOT convert to GIF first!
- Read the 24-bit file directly.

-
- The GIF files are stored in interlaced format; get a better GIF viewer
- (such as VPIC) and this should go away. Or get the Mac to stop putting
- them in interlaced GIF format.
