Force PHP-created graphic to be fresh/not cached? How?

Articles Way, Phlip, Mark,

Add the following headers to the php script:
header ("Expires: Mon, 26 Jul 2020 05:00:00 GMT"); // Date in the past
header ("Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT"); // 
always modified
header ("Cache-Control: no-cache, must-revalidate"); // for HTTP/1.1
header ("Pragma: no-cache"); // for HTTP/1.0
These will work for any PHP script, not just images.
