random .gif banner help

[dynamically_not]

greetings all,
some help with this script would be appreciated;

Its a script that allows the rotation of banners on a webpage, .gif banners in my case, inserted into a table in an Iframe. This is a section of the code:

<SCRIPT LANGUAGE="javascript">
<!-- 
function banner(img_source,url,alt,chance) {
   this.img_source = img_source;
   this.url = url;
   this.alt = alt;
   this.chance = chance;
}
function display() {
   with (this) document.write("<A HREF=" + url + "><IMG SRC='" + img_source + "' WIDTH=460 HEIGHT=115 BORDER=0 ALT='" + alt + "'></A>");
}
banner.prototype.display = display;
banners = new Array();
banners[0] = new banner("files/banner/0.gif",
                        "http://mysite/index.htm",
                        "",
sum_of_all_chances = 0;
for (i = 0; i < banners.length; i++) {
   sum_of_all_chances += banners[i].chance;
}
function display_banner() {
   chance_limit = 0;
   randomly_selected_chance = Math.round((sum_of_all_chances - 1) * Math.random()) + 1;
   for (i = 0; i < banners.length; i++) {
      chance_limit += banners[i].chance;
      if (randomly_selected_chance <= chance_limit) {
         document.write("<A HREF=" + banners[i].url + "><IMG SRC='" + banners[i].img_source + "' WIDTH=460 HEIGHT=115 BORDER=0 ALT='" + banners[i].alt + "'></A>");
         return banners[i];
         break;
      }
   }
}
//-->
</SCRIPT>

My question is: how would i have the link open in the _parent (same window) when clicking the banner. Hope i make sense....

Unless you've put this in a frame, it already will be in the same window, otherwise it will be in the frame that the banner is in. Without testing, if it is in a frame, adding target='_top' to the two <a href tags should do:

   with (this) document.write("<A HREF=" + url + " target='_top'><IMG SRC='" + img_source + "' WIDTH=460 HEIGHT=115 BORDER=0 ALT='" + alt + "'></A>");

and:

      if (randomly_selected_chance <= chance_limit) {
         document.write("<A HREF=" + banners[i].url + " target='_top'><IMG SRC='" + banners[i].img_source + "' WIDTH=460 HEIGHT=115 BORDER=0 ALT='" + banners[i].alt + "'></A>");
