Post Slideshow – Images

Hi,
I would like to add a slideshow exactly like the one used in WordPress.com. Example here: http://refugeproject.wordpress.com/2011/03/24/daniel-ellsberg-arrested/

I’ve tried a few, but none work as well or look as nice as what was in the WordPress.com version.

How do I get this back in my new .org site?

Thanks so much, David
