<ul class="thumb">
    <li><a href="images/main_image1.jpg"><img src="images/thumb1.jpg" alt="" /></a></li>
    <li><a href="images/main_image2.jpg"><img src="images/thumb2.jpg" alt="" /></a></li>
    <li><a href="images/main_image3.jpg"><img src="images/thumb3.jpg" alt="" /></a></li>
    <li><a href="images/main_image4.jpg"><img src="images/thumb4.jpg" alt="" /></a></li>
    <li><a href="images/main_image5.jpg"><img src="images/thumb5.jpg" alt="" /></a></li>

Step2. 创建CSS

#col {
	width: 750px;
	margin: 50px auto 0 auto;
	clear: both;
	padding-bottom: 50px;
ul.thumb {
	width: 600px;
	list-style: none;
	margin: 0 auto; 
	padding: 10px 0;
ul.thumb li {
	margin: 0; 
	padding: 5px;
	float: left;
	position: relative;  /* Set the absolute positioning base coordinate */
	width: 110px;
	height: 110px;
ul.thumb li img {
	width: 100px; height: 100px; /* Set the small thumbnail size */
	-ms-interpolation-mode: bicubic; /* IE Fix for Bicubic Scaling */
	border: 1px solid #ddd;
	padding: 5px;
	background: #f0f0f0;
	position: absolute;
	left: 0; 
	top: 0;
ul.thumb li img.hover {
	background: #666;  /* Image used as background on hover effect
	border: none; /* Get rid of border on hover */
#main_view {
	width: 750px;
	margin: 0 auto;
	padding-top: 20px;
	text-align: center;
	clear: both;

Step3. 插入jQuery和脚本包

<script type="text/javascript">
//Larger thumbnail preview 
$("ul.thumb li").hover(function() {
$(this).css({'z-index' : '10'});
	marginTop: '-110px', 
	marginLeft: '-110px', 
	top: '50%', 
	left: '50%', 
	width: '174px', 
	height: '174px',
	padding: '10px' 
}, 200);
} , function() {
$(this).css({'z-index' : '0'});
	marginTop: '0', 
	marginLeft: '0',
	top: '0', 
	left: '0', 
	width: '100px', 
	height: '100px', 
	padding: '5px'
}, 400);
//Swap Image on Click
$("ul.thumb li a").click(function() {
var mainImage = $(this).attr("href"); //Find Image Name
$("#main_view img").attr({ src: mainImage });
return false;		
<script type="text/javascript" src="http://code.jquery.com/jquery-latest.js"></script>
