Need minor help with my image gallery.

I fell silly asking it but after looking my self over the coding twice I can't figure out where to make the change in it to center my image gallery.

My secound problem is I get seem to change my background color for the image gallery. I'd like to make it match the rest of my page.

The two CSS scripts used to create the Image Gallery are:

http://robinsden.co.cc/Scripts/image_gallery/gallery_style.css
http://robinsden.co.cc/Scripts/image_gallery/jquery.ad-gallery.css

one of the image galleries to show you what it looks like is:

If you need any other of the scripts please let me know.

Thanks you.

#gallery {
background:none repeat scroll 0 0 #E1EEF5;
margin:0 auto;
padding:30px;
}

is what you need. Amend #E1EEF5 to your required colour.
