something like this that i could change to update daily instead of every pageload:
function banner() {
};
banner = new banner();
number = 0;
// bannerArray
banner[number++] = "<a href='http://www.url1.com' target='_blank'><img src='images/banner-1.gif' border='0'></a>"
banner[number++] = "<a href='http://www.url2.com' target='_blank'><img src='images/banner-2.gif' border='0'></a>"
banner[number++] = "<a href='http://www.url3.com' target='_blank'><img src='images/banner-3.gif' border='0'></a>"
banner[number++] = "<a href='http://www.url4.com' target='_blank'><img src='images/banner-4.gif' border='0'></a>"
banner[number++] = "<a href='http://www.url5.com' target='_blank'><img src='images/banner-5.gif' border='0'></a>"
// keep adding items here...
increment = Math.floor(Math.random() * number);
document.write(banner[increment]);
thanks in advance
