- Two suggestions: first, upload the tiff files, which hopefully are 24
- bit instead of 8 bit GIF. Upload without the Mac resource head (if he's
- using the NCSA ftp package, MacBinary OFF) or strip the first 128 bytes.
- Then convert to JFIF (JPEG) which is smaller than GIF and preserves all
- the color information.
-
- The multiple image problem is caused by a broken view which doesn't
- support interlaced format (probably).
