Can you include a file with a query string.. eg
include '/usr/file.php?display=graphic&w=468&h=60'
There are examples here :
http://www.php.net/manual/function.include.php
That discuss this very topic.
No, but there is no need. As long as the variables you desire are already available in the current scope, then they'll be available to the included file.
IOW:
$display="graphic"; $w=468; $h=60; include '/usr/file.php';
