Scrolling Image Gallery

This is a relatively simple project for anyone that knows what they are doing. I require a scrolling image gallery that displays up to 4 images at a time and can be scrolled left or right by the user to display additional images. This gallery is for a Wordpress site, so must be able to operate under the Wordpress environment and must be user editable (for new images to be added or deleted) For an example of what I require please visit [login to view URL] The sort of thing I am after is at the bottom of that page.
