Need help with a banner rotating script

[swizzy]

Does anyone know of a banner rotating script that actually works that I can copy and paste into my script in Dreamweaver.

I've tried several scripts and none of them work.

I especially have troubles with the "body onload" scripts even though I am adding it correctly in the body onload.

I was successful with the following script last year, but god knows how I did it, it just isn't working anymore :^(

<script language="JavaScript">

<!--
function adArray() {
for (i=0; i*2<adArray.arguments.length; i++) {
this = new Object();
this.src = adArray.arguments[i*2];
this.href = adArray.arguments[i*2+1];
}
this.length = i;
}
function getAdNum() {
dat = new Date();
dat = (dat.getTime()+"").charAt(8);
if (dat.length == 1)
ad_num = dat%ads.length;
else
ad_num = 0;
return ad_num;
}
var ads = new adArray(
"images/banner_1.gif","

http://planmagic.com",

"images/banner_2.gif","

http://webquestpro.com",

"images/banner_3.gif","

http://simplythebest.net");

var ad_num = getAdNum();
document.write('<CENTER><TABLE CELLPADDING=0 CELLSPACING=1 BORDER=0><TR><TD '
+'ALIGN=CENTER><FONT SIZE=2 FACE=Arial><B>SimplytheBest DHTML Scripts & JavaScripts is sponsored by: '
+'</FONT></TD><TR></TR><TD><A HREF="'+ads[ad_num].href+'"><IMG SRC="'+ads[ad_num].src+'" '
+'WIDTH="468" HEIGHT="60" BORDER=0 name=js_ad></A></TD></TR></TABLE></CENTER>');
link_num = document.links.length-1;
function rotateSponsor() {
if (document.images) {
ad_num = (ad_num+1)%ads.length;
document.js_ad.src = ads[ad_num].src;
document.links[link_num].href = ads[ad_num].href;
setTimeout("rotateSponsor()",5000);
}
}
setTimeout("rotateSponsor()",5000);
// -->
</script>

Also, does it matter if my banner is gif or jpg? And does the script only work if it is actually online? Why doesn't rotate work in Dreamweaver after you F12 and preview?

Is it best to add the script *within* the website where you want it to appear, or outside the layout table at the bottom?

Please advise, I am at my wit's end!


Any help would be greatly appreciated!
