     *
     *     function upload_info() {
     *         // The returned data needs to be in a very specific format, see below for example
     *         return array(

     *     }
     *
     *    add_filter( 'wpmdb_upload_info', 'upload_info' );

     * @link https://github.com/deliciousbrains/wp-migrate-db-pro-tweaks
