Upload imcheck.cgi to CGIDIR, chmod it 755
Upload im.gif to NON cgi dir
Use the IFRAME line to call imcheck.cgi and
dont forget to change SRC to match your
server.
My site is in frames so i simply added this
IFRAME line to my static left navbar
(eg: leftbar.shtml). I guess there shouldnt
be a problem to add the IFRAME line to your
header in cpanel. Only differens from U is
that i use frames.
