I've got a slideshow of images that i'm attempting to center align. At this time, no following work:

#slideshow {text-align: center}

or setting the design and style via JS. I've got a mockup at http://voicesunited.tk/

How do i center it?

do this

 #slideshow-wrapper { position:relative; margin: 0 auto; }

#slideshow-wrapper { margin: 0 auto; } works in many browsers.
