As I said in my first post, I don't know if I can do this nor do I know if there is anything server specific in my CGI file.
Here a quote from the install README:

QUICK START
------------------------------------------------------------------------
To compile and install mimeTeX
* unzip mimetex.zip in any convenient working directory
* to produce an executable that emits anti-aliased
gif images (recommended)
cc -DAA mimetex.c gifsave.c -lm -o mimetex.cgi
-or- for gif images without anti-aliasing
cc -DGIF mimetex.c gifsave.c -lm -o mimetex.cgi
-or- to produce an executable that emits mime xbitmaps
cc -DXBITMAP mimetex.c -lm -o mimetex.cgi
(For Windows, see "Compile Notes" in Section III below.)
* mv mimetex.cgi to your server's cgi-bin/ directory
* mv mimetex.html to your server's htdocs/ directory
* if the relative path from htdocs to cgi-bin isn't
../cgi-bin then edit mimetex.html and change the
few dozen occurrences as necessary.
Then, to quickly learn more about mimeTeX
* point your browser to www.yourdomain.com/mimetex.html
Any problems with the above?
* read the more detailed instructions below,
or see http://www.forkosh.com/mimetex.html
