This code will put the google image as a link on your blog, to create your personal image link just replace the address to google with your own and replace the image source with your own. Adjust the size of your image to your liking and adjust the position of the layer containing your image to any you want on the page:

<div id="Layer1" style="position: absolute; top: 0; left: 0" align="centre"><a href="<A href="http://www.google.com/"><img">Google"><img src="http://www.google.com/intl/en_ALL/images/logo.gif" alt="" width="158" height="60" /></a></div>

Don't forget to place all of this code inside the 'body' tags.

Regards

Martin
