I sell space on my forum, we are a parenting site for parents of twins triplets and more, so I use my own ads custom made for my forum. Here is the java I use to display them.
<script language="JavaScript">
i = 4 // Number of banners that you have
banner1 = new Image();
banner1.src = "image one here";
banner2 = new Image();
banner2.src = "image two here";
banner3 = new Image();
banner3.src = "image three here";
banner4 = new Image();
banner4.src = "image four here";
links = new Array
links[1] = "url 1"
links[2] = "url 2"
links[3] = "url 3"
links[4] = "url 4"
text = new Array
text[1] = "alt text"
text[2] = "alt text"
text[3] = "alt text"
text[4] = "alt text"
function randombanner(){
var randomnumber = Math.random();
i = Math.round( (i - 1) * randomnumber) + 1;
document.banner.src = eval("banner" + i + ".src");
}
function startTime(){
var time= new Date();
hours= time.getHours();
mins= time.getMinutes();
secs= time.getSeconds();
closeTime=hours*3600+mins*60+secs;
closeTime+=5;
Timer();
}
function Timer(){
var time= new Date();
hours= time.getHours();
mins= time.getMinutes();
secs= time.getSeconds();
curTime=hours*3600+mins*60+secs
if (curTime>=closeTime){
if (i < 4){
i++;
document.banner.src = eval("banner" + i + ".src");
}
else{
i = 1;
document.banner.src = eval("banner" + i + ".src");
}
startTime();
}
else{
window.setTimeout("Timer()",1000)}
}
function clickLink(){
top.location = links[i]
}
function descript(){
window.status = description[i]
}
// -->
</script>
<body onLoad="randombanner(); startTime();">
<center><a href="your url here" onClick="clickLink(); return false;" onMouseOver="descript(); return true;" onMouseOut="window.status=''"><img src="your imgar here" border=0 name="banner"></a></center>
