Does anybody know how to set Mosaic up to execute two programs consecutively,
say wincode and wingif?

I guess "they" heard you!  The ACS gopher now sports a fancy new face, which
has uuencoded gif formated files available.  Here is the READMEgif from the
gopher

The supplementary material for Journal of the American Chemical Society
can now be retrieved in GIF format. Because of the difficulties which
many have experienced in handling TIFF/G4 files, we have developed a
procedure to deliver the files in uuencoded GIF format. This is
somewhat of an experiment, since we need to see how the new procedure
affects the load on the gopher server, and how people are able to use
the new format. Please send us your comments on this new format to
gop…@acsinfo.acs.org.

Here is how the new procedure works:

1) We are still storing the files as TIFF/G4.

2) A parallel set of directories, under the heading "Supplementary
Material in GIF format" have been created. While TIFF/G4 images are
named with the extension "tif", the GIF images are named with the
extension "ugif". When you request a "ugif" file, a program will be
executed to convert from TIFF/G4 to GIF, uuencode the file, and deliver
the resulting file. Use your gopher client to this as a file on your
system.

3) To display the page, you must first uudecode the file. There are a
number of public domain packages to perform this decoding. On the
Macintosh, uulite can be used. On DOS computers, a uudecode program is
part of the uuexe package. Both programs are available on the "Software
Archives at MERIT" gopher server from the University of Michigan. The DOS
program is available under the path /msdos/util/unix/uuexe522.zip, while
the Macintosh program can be found under the path
/mac/util/compression/uulite1.5.cpt.hqx.

4) When you uudecode the file, a GIF file will be created. This format
can be handled by a number of viewers, such as cshow and wingif under
DOS/Windows, and jpegview on the Macintosh.

NOTE: Because of the way this procedure is accomplished, it is
possible only via gopher, and not anonymous ftp.

For the PC, the latest version of VUIMG (available at simtel) will
display these. Nothing else I have tried will. Makes you wonder
whether ACS has thought this through, doesn’t it?

yes it does.  I tried one of the programs listed by the ACS gopher server
for viewing the tiff files, to no avail.  On a Mac, these files show up
as jpeg files, but no jpeg viewer I have will read them.

I’d strongly suggest they go to using straight *.gif files, since there are
so many viewers on so many platforms for gif files. (Unless there is
a copyright problem)          

Also, as I understand it, the people putting the JPEG standard together are
doing so in order to establish a graphics standard in the public domain.  That
might also be a good standard to consider, as it is used widely on usenet
for graphics file exchange.
