SSI example:
<!--#set var="myserver" value="http://$SERVER_NAME:$SERVER_PORT/" -->
<div>
SSI: <img src="<!--#echo var="myserver"-->logo.png"
width="417" height="137" alt="Logo">
</div>

PHP example:
<?php
$myserver = 'http://'.$_SERVER["SERVER_NAME"].
':'.$_SERVER["SERVER_PORT"].'/'
?>
<div>
PHP: <img src="<?php echo $myserver ?>logo.png"
width="417" height="137" alt="Logo">
</div>

All my humor is based upon destruction and despair. If the whole
world was tranquil, without disease and violence, I'd be standing on
the breadline right in back of J. Edgar Hoover.
