Fancybox - how can I show thumbnails by default?

Question

How can I show these thumbnails by default?

Live code example here
I am using Fancybox api for open lightbox by click.

        $.fancybox.defaults.buttons = ["zoom", "thumbs", "close" ];

        $('.fancybox-btn').click(function () {
            $.fancybox.open([
                {
                    src  : 'http://placehold.it/300x200?text=1',
                    opts : {
                        thumb   : 'http://placehold.it/300x200?text=1'
                    }
                },
                {
                    src  : 'http://placehold.it/300x200?text=2',
                    opts : {
                        thumb   : 'http://placehold.it/300x200?text=2'
                    }
                }
            ]);
        });

Answer 1

Add thumbs : { autoStart : true, }, option to second argument of $.fancybox.open:

{
    loop : false,
    thumbs : {
        autoStart : true,
    },
}
