為了減輕server loading
圖片的顯示 加上了JQuery外掛 Lazy Load
讓圖片延遲載入

瀏覽器 拉到該可視範圍內
圖片才載入

前提必須有jquery

接著需下載
queryLoader.js
jquery.lazyload.mini.js

塞進所用呈現的檔案內

 <head>

	  <title>test</title>

	  <script type="text/javascript" src="jquery-1.2.6.pack.js"></script>

	  <link rel="stylesheet" href="queryLoader.css" type="text/css" />

	  <script type='text/javascript' src='jquery.lazyload.mini.js'></script>

	</head>

並加上

 <script type="text/javascript">

	  $("img").lazyload({ effect: "fadeIn" });

	</script>

img就是html的

<img src="/images/001.gif" />
