How to get image by id using image_advanced?

I have a multiple section for selectbox and image_advanced

then below is the output of the data:

Array
(
    [0] => Array
        (
            [album_color] => orange
            [album_images] => Array
                (
                    [0] => 468
                    [1] => 469
                )

        )

    [1] => Array
        (
            [album_color] => gray
            [album_images] => Array
                (
                    [0] => 470
                    [1] => 469
                )

        )

)

How can i display the image without looping? for example i only want to get the first image in the album orange(id is 468)

You can use this code:

$groups = rwmb_meta( 'group_id' );
$first_group = !empty( $groups ) && is_array( $groups ) ? reset( $groups ) : array();
$images = !empty( $first_group['album_images'] ) && is_array( $first_group['album_images'] ) ? $first_group['album_images'] : array();
$first_image = !empty( $images ) && is_array( images ) ? reset( $images ) : 0;

echo wp_get_attachment_image( $first_image, 'thumbnail' );

PS: Are you using the Group extension? I see you didn't purchase it.
