Either: 1. a.php <img src="b.php?id=<?php echo $building; ?>" /> --or-- 2. a.php echo '<img src="b.php?id=' . $building .'" />'; Then, whicher you choose above: b.php: $build = $_GET['id']; -- Thanks! -Shawn http://www.spidean.com -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
