This is a full browser width slide show, which you can create in Muse:
Since slideshows aren’t completely responsive for now, you have to reposition the thumbnail container breakpoint-wise
Here you have a sample site, showing the construction: http://animated-thumbnails.businesscatalyst.com/index.html
You may download the corresponding .muse file directly from this site.
or.druker: If you already visited the thread, please read my answer again: I managed to mimic the animated thumbnails too. Of course the sample assets have to be optimised. Especially the „timing“ of the animated thumbnail has to be synchronised with the duration of the single images. But the „quick & dirty“ page shows, that it is possible to come very close to Apple’s slideshow.
Thanks ! It was helpful and kind of you
