Magento batch update category quick script

Just to supplement another post we made on bulk creating categories, below is a script used for bulk updating and attaching images to categories based on a specific CSV.

There is no documentation to go with this code, I'm simply posting it because a subscriber has requested it.

<?php
define('MAGENTO', realpath(dirname(__FILE__) . "/.."));
require_once MAGENTO . '/app/Mage.php';

umask(0);
Mage::app()->setCurrentStore(Mage_Core_Model_App::ADMIN_STORE_ID);
$write = Mage::getSingleton('core/resource')->getConnection('core_write');
$count = 0;
$headers = array();
$file = fopen(MAGENTO . '/var/import/importcats.csv', 'r');
$_category = Mage::getSingleton('catalog/category');

while (($line = fgetcsv($file)) !== FALSE) {
    $count++;

    // First header row

    if ($count == 1) {
        foreach($line as $id => $col) $headers[$col] = $id;
        continue;
    }

    $_category->load($line[$headers['ID']]);
    $_category->setMetaTitle($line[$headers['meta_title']]);
    $_category->setMetaDescription($line[$headers['meta_description']]);
    $_category->setDescription($line[$headers['additional_description']]);
    $_category->setUrlKey($line[$headers['url_key']]);
    $sql = "INSERT INTO catalog_category_entity_varchar 
 (entity_type_id, attribute_id, store_id, entity_id, value) 
 VALUES
 (9, 113, 0, " . $line[$headers['ID']] . ", '" . $line[$headers['image']] . "')
 ON DUPLICATE KEY UPDATE value = '" . $line[$headers['image']] . "';
 ";
    $write->query($sql);
    $src = '../media/import/cat_imgs/' . $line[$headers['image']];
    $dest = '../media/catalog/category/' . $line[$headers['image']];
    copy($src, $dest);
    $_category->save();
    echo "Completed " . $line[$headers['name']] . "<br />";
}
