Changed keyboard nav

Browse Source 
In conjunction with styles.css change, changed W, and S keys to scroll image vertically and removed page change from Up and Down, leaving A, D, Left, and Right as keys for changing page. Page returns to the top when changing page. W and S scroll behavior is not smooth. Up and Down scroll relies on browser's in-built keyboard scrolling functionality.
