Need a simple slideshow plugin

Hello I run the site https://xtmag.net/ and I have been trying in vain to find a simple slideshow plugin in order to load photos from my gallery or computer to upload photos to a page or post. The problem I have been running into is all the plugins have no instructions on how to use the application, therefore I am lost. If anyone can lead in me the right direction that would be great. Ideally I would like to find a plugin that works the same way the [slideshow] feature does in wordpress.com.
