Nextgen Gallery Pics show up way to the left.

Hi… How can I make photos show centered? I saw somoene else’s site and there was a boarder around the photos all the way to each side and they were centered nicely.

Here’s a link to the gallery I’m having issues with.

When you click the thumbnails, they show up to the absolute left and I don’t see where to fix that in the plugin controls or the css. I must be missing something.

Thanks in advance!
