Well I've never had a use for cookies, so I don't really know how to create them.

Well can somebody help me? This is an example of a code I am trying to make, and I need it to make it so the banner saves as it is selected.


<script type='text/javascript'>
var td = document.getElementsByTagName('td')
function bannerchanger(n)
{
td[1].getElementsByTagName('font')[0].innerHTML = "<img src='http://img167.imageshack.us/img167/9067/bannercyanmw6.gif'>";
}
document.write('<a onclick="bannerchanger()">Change It</a>')
</script>

Anyone help? And if somebody would be as kind as to help me, I would also like to learn how to write the cookie and get to know what the coding part of it really means. Thanks.
