JQuery Mosaic Collage Help

How can I insert a jquery slider that depicts featured images in a fashion similar to the one on https://www.engadget.com/ and https://tympanus.net/Tutorials/HoverSlideEffect/ where the featured images are different sizes, but together they make a solid rectangle. Also, I don’t want that hover effect in the second link, I just want the geometry of it. Any ideas of how I would go about finding this and where I could get it from? What is the name of this type of slider? I have been searching the internet for days and I cannot find it.
