Jquery - Modify Jquery Div Galley, Add auto Slide Function

On the Gallery there are 5 Div's that use the "fadeIn and fadeout" Jquery Properties. This is controlled by the blue arrows on the side to go to the next or last Div. I need this function either added to or re-written so every 10 seconds the javascript automatically slides to the next div. However if the web user hits a blue "next" arrow key, the automatic slide must stop. The website is [login to view URL] the gallery is the one that starts ewith "Earth Friendly" witrh blue arrows. You can get the source from there to preview but I will provide full test files.
