http://www.balupton.com/sandbox/jquery_lightbox_bal/demo/

使用方法
先下载 jQuery lightBox plugin

leandrovieira.com/projects/jquery/lightbox/
http://www.balupton.com/sandbox/jquery_lightbox/

然后在网页中写入:
<script type="text/javas

cript" src="http://yourdomain/jquery.js"></script>
<script type="text/javascript" src="http://yourdomain/jquery.lightbox-0.3.1.js"></script>
<link rel="stylesheet" type="text/css" href="http://yourdomain/jquery.lightbox-0.3.css" media="screen">
<script type="text/javascript">
     $(function() {
         $(‘#id名 a’).lightBox();  
     });
</script>

上面代码完成后,在网页中加入图片:

or <a rel="lightbox" href="images/mountain-large.jpg" >

<div id="id名">
<a href="" title="">
     <img src="" width="" height="">
</a>
</div>

lightbox还加入了:

     *改变颜色重叠: overlaybgcolor : ‘ # fff ‘
     *覆盖的透明度: overlayopacity : 0.6
     *文本1 : txtimage : ‘图片’
     *文本2 : txtof : ""….

$(function() {
     $(‘#gallery a’).lightBox({
         overlayBgColor: ‘#FFF’,
         overlayOpacity: 0.7,
         txtImage: ‘图片’,
         txtOf: ‘。。。。。。。。。。’
         }
     );
});
