+ *  1) Back up your images and your database.
+ *  2) Run update-image.php first.
+ *  3) Edit the configurable values below.
+ *    1) $minimum_nid is the node ID at which this script will start checking.  
+ *       Smaller nids will be ignored.
+ *    2) $nodes_per_run is how many nodes to check per page load.
+ *  3) Copy this file to your Drupal installation root and run it from a web browser.
+ *  4) Reload this page as necessary.
+ *
+ * Warning:
+ *  This script is provided AS-IS.  It could screw up your data,
