We do it here - you create a class containing your logo, then use the images as backgrounds to tables.
View the source of our page here and see how we do our header.
Then in our stylesheets we've added a class for each logo (with URLs to matching graphics):
<br />.devswoosh {<br /> background-image: url(../images/cssgraphics/koniro/devswoosh.gif);<br /> background-repeat: no-repeat;<br /> background-position: right top;<br />}<br /><br />.devlogo {<br /> background-image: url(../images/cssgraphics/koniro/logo.gif);<br /> background-repeat: no-repeat;<br /> background-position: left top;<br />}<br />
