Since we are on this forum, I'll take a bite: Carousels need to die. Everyone hates them, no one interacts with them unless they have to. The carousel doesn't work for the user and it doesn't work for the product. http://shouldiuseacarousel.com/ https://www.dgtlnk.com/blog/website-carousel/ The plane model is nice.
On mobile, whether the article is long or not, it's nice being able to quickly scroll back to a section of text to find something you read previously; if there's 25 pictures in the way, that gets obnoxious quickly, and I'm more likely to just leave.
Having a carousel means the user can see all the pictures (used to good effect with overviews and varying levels of detail/zoom/cutout); scroll horizontally (or tap icons, but scrolling would be better) for more images and vertically for more text. A way to improve this one would be to make it an embed that can enlarge itself to take up the full screen and restyle itself vertically or horizontally; I know I've seen this functionality somewhere, possibly a php image hosting script.
