Gallery Slide show

Hi there

I love my theme but I am just having a little issue with the gallery, I want a slideshow so i don’t have the three columns of pictures at the bottom of the page. I had Jetpack plugin on and saw in previous comments that this conflicts, I turned it off and still no joy! please can someone point me in the right direction.
