Problems with squidGuard and squidGuard.cgi

[cell]

Hello , i'm on freebsd 5.4 and i tried to configure squidGuard but i have a problem with squidGuard.cgi.I have this squidGuard.cgi http://ftp.teledanmark.no/pub/www/proxy/squidGuard/contrib/squidGuard.cgi .In configurable options i have that :

# CONFIGURABLE OPTIONS:
#
@supported   = (                                                                     # "en", "fr", "de", "nl", "no" etc.
                "fr (Français),",
                "en (English),",
                "de (Deutsch),",
                "nl (Nederlands),",
                "no (norsk)."
               );
$image       = "/images/blocked.gif";                                          # RELATIVE TO DOCUMENT_ROOT
$redirect    = "http://192.168.1.2:88/images/blocked.gif";             # "" TO AVOID REDIRECTION
$proxy       = "bsd2.mydomain";                                               #
$proxymaster = cell at mydomain;                                             #
$autoinaddr  = 2;                                              # 0|1|2;

I have created a directory "/usr/local/www/data/images" but i haven't got picture named "blocked.gif" , i don't know where she is.
And when i run this script cgi , i have that in logs apache :

[Fri Jul 22 18:55:24 2005] [error] [client 192.168.1.3] Premature end of script headers: squidGuard.cgi


Anyone have an idea for this problem ?
