Noob looking for a nice slideshow

I’m really needing a good, simple, and free slideshow for my WP blog. I’ve looked forever, but just can’t seem to find something that will work.

Here are a couple examples?

https://www.hiphopmusicdotcom.com/
https://hiphopmakers.com/
https://justintadlock.com/options/

The third one is what I’m trying to use on one of my new blogs (rapblogger.com) but it just doesn’t seem to be working out well.

If figured before I fooled with it for days, I’d see if you guys had any pointers, or could pick out which script those other two sites are using.

Thanks!

Josh
