Ok then.
CSS:
.cornerImage
{
position:fixed;
z-index:1000;
right:0px;
bottom:15px;
}
*html .cornerImage { position: absolute; }
HTML:
<body>
<div class="cornerImage" id="forIe">blah</div>
<div id="content">
<!-- Your content here -->
</div>
</body>
For IE you'll need to position this thing with the help of JavaScript :( Something like:
var sizeOfMyAd = {Put height here};
function ieFix() {
var y = document.documentElement.scrollTop + document.body.offsetHeight - sizeOfMyAd;
document.getElementById('forIe').top = y + 'px';
}
setInterval(ieFix, 100);
