  1. Try this…

    <ul class="basic-gallery text-center">
    <?php 
        $output = '';
        foreach( $header_images as $id => $content ){
            $output .= '<li>'. wp_get_attachment_image($id, 'large');
            $image = get_post($id);
            $output .= '<span class="caption>'.$image->post_excerpt.'</span>';
            $output .= .'</li> ';
        }
        echo $output;
        $output = '';
    ?>
</ul>

    Output your caption in whatever container you want, I just used a span as an example.
