Is it compiled for windows? And are you writing
file.htm and image.gif to stdout? I had the same problem
with my own little server <www.forkosh.com/mimetex.html>
getting it to run on windows (in addition to linux).
And you found the problem yourself mentioning \n in one
of your followup posts.

In windows, stdout is ascii, not binary. You have to
#include <fcntl.h> and #include <io.h>, and then
issue a _setmode(_fileno(stdout),O_BINARY) to make it binary
for windows. Otherwise windows gives you the "newline problem",
i.e., every time your gif image happens to contain a byte
that's a carriage return, windows will tack on an extra linefeed
for you. And that'll totally mess up your gif.
