It's better to send the file, as postscript (for ghostscript), or with
recent patches, as TIFF-F.

You should get permission denied.  If you want to provide unrestricted
access, you need to change the default file mode.

Yes they are; there is no standard for ftp directory listing formats
as they were not intended for machine use (NLST format is intended
for machine use, but gives the name and no additional information).  Your
browser probably understands Unix and MS-DOS, and possibly NT and a few 
more, formats, but not Hylafax format.

As a result, the browser mis-parses the directory listing and thinks that
the whole of the line is the file name.  Use a command line ftp client,
not a GUI browser.
