On the following website I saw a very nice gallery:
I searched on the internet but I’m not able to find anything similar to this.
I use Foundry as theme and you can choose with the build in gallery a ‘featured image’. But this one is not responsive so you cannot scroll through the images. Gallery Stack 3 with the slick slider would be a nice option but it doesn’t fit well on my iPhone and you cannot make the displayed image full screen.
Does someone know something that comes close to example on the website?
