I am sure that there is a Javascript which can do this trick, I made 2 scripts here and you can customize the way you want!
Script 1 -- Banner rotate script when everytime the page is load, the banner rotates!
put this script in <body></body> section
<script language="Javascript">
<!--
var core = 0;
link = new Array(
"http://www.yahoo.com",
"http://www.pokemon.com",
"http://www.php.net"
);
image = new Array(
"yahoo.jpg",
"pokemon.jpg",
"php.jpg"
);
text = new Array(
"Yahoo",
"Pokemon",
"PHP"
);
var time = new Date();
var core = time.getSeconds() % image.length;
var ranlink = link[core];
var ranimage = image[core];
var rantext = text[core];
document.write('<a href=\"' +ranlink+ '\"><img src=\"'+ranimage+'\" border="0" alt=\"'+rantext+'\"></a>');
//-->
</SCRIPT>
Link array stores the information of the url of the banner
image array stores the banners
text array stores the alternative text when you mouseover it
Script 2 --- Banner rotate script that rotates banners every X seconds!
put this script in <head>/head>
<script language="Javascript">
<!--
var date = 0;
var number = 0;
function rotate()
{
image = new Array()
image[0]=new Image()
image[0].src="yahoo.jpg",
image[1]=new Image()
image[1].src="pokemon.jpg",
image[2]=new Image()
image[2].src="php.jpg"
var time = new Date();
document.banner.src=image[number].src
if(number ==2 )
number=0
else
number++
setTimeout("rotate()",3000)
}
function linktoweb()
{
link = new Array(
"http://www.yahoo.com",
"http://www.pokemon.com",
"http://www.php.net"
);
window.location.href=link[number]
}
//-->
</SCRIPT>
change <body> into <body onload="rotate()">
put this script in <body></body>
<a href ="javascript:linktoweb()">
<IMG NAME="banner"
BORDER=0
HEIGHT=60
WIDTH=468
SRC="PChome.jpg"></a>
and it should be self-explanatory
hope this helps!
