I want to make something like this:

It displays new updates to the game, and I want it so you can scroll through it like a slideshow, I've already gone onto https://community.fandom.com/wiki/Help:Galleries,_Slideshows,_and_Sliders and it didn't help at all, it just said to go onto the right 'tail' and press add features and media, which it doesn't say anything but 'save page' on the right tail, so I'm lost, I've uploaded the pictures to the upload page but when I click on gallery it just comes up with a search button and When i search the file up nothing comes up..

Why isn't there just a button that makes a slideshow automatically? Seems really convoluted and pointlessly confusing.
