Single Horiz. Sliding Image gallery

http://www.mateuarchitecture.com/

Please take a look at the above site. Once past the intro pages their image gallery has 3 horiz. lines of images. The images move left when you move the mouse left and right when moving the mouse right. I am only looking for a single line that will act like what they have on this site. I am sure that this has been posted somewhere on here but I have now looked for 2 days for some kind of help and have not found it yet. Thanks to all for any help you may provide. I am a newbie when it comes to advanced flash effects but learning fast.
Thanks,
Jim
