Delete folder/files on resource deletion with plugin?

<?php
$dir  = $modx->getOption('base_path') . 'assets/p-images/';      //original images
$files = glob($dir . "*.jpg"); //get all jpg from dir
$id = "/" . $id . "-"; //make sure if this is really correct number in /xxx-name.jpg

foreach($files as $image) {
   if (strpos($image,$id)) {      //if correct string in path...
   unlink($image);  //delete image in p-images
   $image = str_replace("p-images", "w-images", $image); //change path
   unlink($image);   //delete image in w-images
  }
}
return;
