One comment. I found that when you don't have javascript enabled it shows no image at all. So what I have done is found:
Code:
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
showImage();
// End --></script>
And added this right after:
Code:
<no script>
<center><img src='/images/put_your_default_image_name_here'></center>
</no script>
I think this should work to keep the site consistant when a non java script enabled person visits your site. Also note that the <center> and </center> are optional. I just use them on my board because I like my logo centered.
