Can somebody give me the code or show me where to get a cgi script that will show an specific image when i load up my page, then the next time I load up my page, a different image is shown instead... this would occur until say I had seen all 7 images, then the cookie counter would be reset back to 0 and the first image would be shown again and so forth.

Go to www.cgi-resources.com and search for this kind of scripts. There are many free scripts for image-rotation.

randimg.pl generates a random image from the data.txt file and displays
the image with its height, width and alt tag. Included in this version
you can add new image information without having to edit the data.txt
file. Requires SSI.

In the script, you have to defined only one variable:
      $imgfile = 'data.txt' (same directory)
      $imgfile = '/complete/path/to/data.txt' (others)
            The location of the data.txt used to hold all the
            banner information.

In the document you want a banner to appear, call the script in this
      <!--#exec cgi="/cgi-bin/randimg.pl"-->
Different servers have different ways to call the script so check with
your server administrator first.

# randimg.pl v1.5 28/12/98
# mpeh@iname.com

$imgfile = 'data.txt';
$command = "$ENV{'QUERY_STRING'}";       

if ($command eq 'add') {
  else {

sub OutputImg {
      open(FILE, $imgfile) || die "Can't open $imgfile";
      $file = <FILE>;
      @stuff = split(/,/,$file);
      srand(time ^ $$);  
      $choice = rand(@stuff);

      $chosen = @stuff[$choice];
      @part = split(/;/,$chosen);

      print "Content-type: text/html\n\n";
      print "<img src=\"@part[0]\" width=\"@part[1]\" height=\"@part[2]\" alt=\"@part[3]\">\n";

sub ParseForm {
      read(STDIN, $buffer, $ENV{'CONTENT_LENGTH'});
      @pairs = split(/&/, $buffer);
      foreach $pair (@pairs) {
            ($name, $value) = split(/=/, $pair);

            $value =~ tr/+/ /;
            $value =~ s/%([a-fA-F0-9][a-fA-F0-9])/pack("C", hex($1))/eg;
            $form{$name} = $value;

sub NewInfo {
      open(FILE, $adfile) || die "Can't open $adfile";
      $lama = <FILE>;
      $baru = ",$form{'image'};$form{'width'};$form{'height'};$form{'alt'}";
      open(FILEN, ">$adfile");
      print FILEN "$lama$baru";

sub PrintDetials {
      print "Content-Type: text/html\n\n";
      print "<html>\n";
      print "<head><title>Completed!</title></head>\n";
      print "<body bgcolor=\"#ffffff\" text=\"#000000\">\n";
      print "<br><br><center>\n";
      print "<table cellpadding=0 cellspacing=0 width=\"65%\">\n";
      print "<tr><td bgcolor=\"#001549\">\n";
      print "<center><font face=\"arial,verdana\" size=\"3\" color=\"#ffffff\"><b>DATA.TXT UPDATED!</b></font></center>\n";

      print "<p><a href=\"$ENV{'HTTP_REFERER'}\">Click here to add more.</a>\n";
      print "</font></blockquote>\n";
      print "</td></tr>\n";
      print "</table>\n";

you can also try javascript:



function pickimage()      {
      var imagenumber = 3 ;
      var image = "image.html" ;
      var randomnumber = random() ;
      var imageselect = Math.round( ( imagenumber - 1 ) * randomnumber ) + 1 ;

      if  ( imageselect == 1)   { image = "start_image.jpg" }
      if  ( imageselect == 2)   { image = "image_before.gif" }
      if  ( imageselect == 3)   { image = "image_after.gif" }

      document.write('<IMG SRC="' + image + '" WIDTH=90 HEIGHT=70 BORDER=0>') ;}

function random()
  var today = new Date()
  var seed = today.getTime() + today.getDate()
  seed=(seed * 29  + 1) % 1024
  return seed/1024



<SCRIPT LANGUAGE="JavaScript">pickimage()</SCRIPT>
