I’m writing this post for people that are new and cant seem to find updated posts, especially for 2021. Here is a current up to date link to a plugin you can use for a photo slideshow. I love this plugin, because I needed help with a slideshow after uploading pictures to an option set, and then wondering how to do it. The other plugin Slick Slideshow is trash, and there is no help on it. This app will make you much more happier with your project, yourself and life… lol
This link will bring you to an outdated post, but most recent. Enjoy!
