从网上下载了一个jquery的图片放大显示插件，效果如下

前台代码调用：

先引入js

<script type="text/javascript" src="../js/jquery-1.2.6.pack.js"></script>
<script type="text/javascript" src="../js/jquery.imagePreview.1.0.js"></script>
<script type="text/javascript">
$(function(){
 $("a.preview").preview();   
});
</script>

html页面代码

 

  <div class="zxx_out_box">
    <div class="zxx_in_box">        
        <h3 class="zxx_title">图片放大显示的jQuery插件演示页面</h3>
        <div class="zxx_main_con">
            <div class="zxx_test_list">
