rushingparachutes on "What kind of picture slideshow plugin does this twenty twelve theme use?"

I need a slideshow plugin where it can fit a full image and when you click next, it will show another full image. (responsive for twenty twelve)
I also need the little bullets below the gallery just like it's shown on the pic above.

Any recommendation is appreciated, thanks alot!
