 * In wp-admin/includes/media.php
    There resides these lines.
 *     ```
       if ( ! empty( $meta['title'] ) )
       $title = $meta['title'];
       ```
   
 * I want that changed to:
 *     ```
       if ( ! empty( $meta['file'] ) )
       $file = $file['file'];
       ```
   
 * I know this works for what im doing, but would like some way to evoke this without
   changing the core file. Is there a way to do this?
 * Thanks.

 * Would the `wp_generate_attachment_metadata` filter do?

 * I do not know nor do i know exactly what code to use or where to place it. i 
   know that filters are often in functions, but I really would need some code and
   know where to place it.
