Slideshow Problem

Hi,

I need to center my site’s slideshow which is currently stuck to the left hand side of the page ever so slightly, I need to move it right a little bit to make it look right. I’ve tried doing this with the header.php and style.css but it only ends up making the page mess up, like the News and Reviews lists would jump across and so on.

Here’s what the page looks like now

Do you have any ideas what I should alter to fix this?

Thanks
