How to change header image into a slideshow?

I’m newish to wordpress and just facerolling through it. Before I was trying to do too much on my site to tie it into my social media accounts and make it “look cool”. Now I’m simplifying it down to the art portfolio that I want to make. I liked the look of “Arcade Basic” as the theme to my site. I like the big header image area and that it doesn’t leave big blanks when my posts didn’t have featured images. While the current header is a nice collage of some of my works, I’d rather have a slideshow that links to categories in my site. One for 2d works, another for 3d works, and so on as I need them. I’ve been trying to find a plugin that will do this but no luck so far (tried a few and they tend to make a slideshow under the heading on non default pages). Of course it will likely get rid of the titles and “see more” button and I’d be OK with that. Thanks to anyone that helps.
