//網頁中請加<SCRIPT src='chang_image.js'></SCRIPT>
//要顯示的位置請用一張和背景相同顏色的圖show出來我是取名為empty.gif(我新增的)  你可以改檔名
//但底下的程式EmptyImage.src="../image/empty.gif";也要改成你的檔案注意路徑也要對喔
//如 <img src="../image/empty.gif" name="DisplayImage" > (name="DisplayImage" 為必加要一樣喔)
//在超連結中加上onmouseover="ChangImage(1)" onmouseout="ChangEmptyImage()" 1表底下Array中的第一個圖 就是你想顯示的圖 
//如 <a href="ep4.htm" class=yieh1 onmouseover="ChangImage(1)" onmouseout="ChangEmptyImage()">Oven</a>
//將所有要顯示的圖加到ImageSrc的Array()中如Array("../image/26mach01s.gif")包含路徑每一個請用,隔開
