I was wondering is there a way to create a similar carousel gallery in Webflow? So that the next and previous images are visible, and the hight of the gallery is always the same (thus fitting both vertical & horizontal photographs)?
Swiper is a great choice IMHO since it is actively maintained and open source. Slick is rather stale (2 + years stale). Another choice I would recommend is tinyslider (a replacement for Owl Carosel.
Flickity is a good choice (commercial license required for commercial projects). Here is a Flickity Slider Demo (CMS Items) read-only project that demonstrates how to use. It is really easy to set up. Took me less time to build than write this post.
