Manual Image Crop

Doesn't seem to work with add_image_size when used with a child theme's function.php using code like below:
/*---------------------------------------------*/
/* ADD CUSTOM IMAGE SIZES
/*---------------------------------------------*/

if ( function_exists( 'add_image_size' ) ) {
	add_image_size( 'facebook-image-page', 470, 470 );
}

add_filter( 'image_size_names_choose', 'insert_custom_image_sizes' );
function insert_custom_image_sizes( $sizes ) {
	global $_wp_additional_image_sizes;
	if ( empty($_wp_additional_image_sizes) )
		return $sizes;

	foreach ( $_wp_additional_image_sizes as $id => $data ) {
		if ( !isset($sizes[$id]) )
			$sizes[$id] = ucfirst( str_replace( '-', ' ', $id ) );
	}

	return $sizes;
}
