/* SPRITE STYLE IMAGE ROLLOVER
 *
 * One very wide gif image displayed as a background image which contains all 
 * map rollover variations is dynamically repositioned onmouseover. The viewport
 * is the width of one map image, meaning the remainder are off-screen.
 * The positionID is multiplied with the mapImageWidth to scroll the background image by 
 * the required amount to position it within the viewport.
 *
 *    default:      [#]######
 *    positionID=2: ##[#]####
 *    positionID=4: ####[#]##
 *     etc..
 * 
 * Note that the background is attached to the <img> with id=mapImage
 * and src= to a transparent GIF image. The width attribute specifies
 * the viewport width.
 * 
 * Producing one large gif of 39kb loads quicker over one http txn 
 * rather than 7 smaller gifs with a sum of 45kb.
