My suggestion is to comb the web for a copy of Ghostscript for one of your
Unix boxes.  The script ortep2html that you probably saw uses Ghostscript to
convert a lot of orteps in one go, but you can do it manually if you need to
use just one or two.

I'm guessing you saw my URL 

	http://elmo.ucsc.edu/~adrs/ortep2html.html

which talks about my script (probably the first Perl script I ever wrote). 
In it, there's a link to the Ghostscript site, from which you should be able
to get a copy that will run on one of your machines.

From my script, I pulled the following lines, which constructs the arguments
you need to give ghostscript to convert a PostScript ortep figure into a gif
file:

	$bigcommands="-q -sDEVICE=gif8 -sOutputFile=$bigname"
	open(CMD,"|gs $bigcommands $psfile");

So, $bigname is a variable holding the name of your output file, and $psfile
is the name of the PostScript file.  So, substituting $bigcommands into this
second line, you get

	open(CMD,"|gs -q -sDEVICE=gif8 -sOutputFile=$bigname $psfile");

Now, trim all the chicken fat from this (which is just Perl to do the batch
processing) and you get:

	gs -q -sDEVICE=gif8 -sOutputFile=$bigname $psfile

So, get a copy of GhostScript (ie, gs in the line above), figure out how to
get it running on your computer, use the filenames you want in place of the
variables above, and  you are in business.  

The image file viewer xv might also let you open a PostScript file and save
it as a GIF (or TIFF or just about any other damn format) too, but the catch
is that it also calls GhostScript to do it.  It might just be a more
convenient front-end than the command-line approach given above.

If UNIX command-line utilities and UNIX-pipes don't bother you, you could
also get a copy of the pbm utilities, and use pstopnm and pnmtotiff to get a
TIFF file, then use something else (like xv) to get your GIF from the TIFF:

	pstopnm postscriptfile | pnmtotiff > tifffile

[ . . . ]

Bug the computer people there for help getting GhostScript installed, and xv
if you don't have it, either.  Both are mature, commonly used pieces of
software that they should be able to download pre-compiled.  There's
absolutely no reason you should not be able to do this--people know how to
do it, and do it all the time.  Besides, I'd like to see some of your
structures without having to schlep over to the library!
