我利用代码最了下效果，点击左右可以切换。需要自己修改图片大小。
[color=Red]在文章里面添加代码： （调用一个页面）[/color]
<iframe height="520" border="0" src="/photo/14/js.htm" frameborder="0" width="640" scrolling="no"></iframe>
[color=Red]然后修改根据自己网站修改 js.htm 和里面的图片链接。
代码如下：[/color]

[color=Red]以下是说明：[/color]
<p><img id="img1" src="../../images/tjj.jpg" /></p> 这里是背景图片，可以随便换！
var arrowImage1 = new Image();arrowImage1.src = "../../images/arrow001.gif"; 左箭头
var arrowImage2 = new Image();arrowImage2.src = "../../images/arrow002.gif"; 友箭头
if (i==imgs.length-1) alert('已经是最后一张了'); 显示的字
else img.src = imgs[++i];
}
imgs = new Array('1.jpg','2.jpg','3.jpg'); 自己处理图片和js.htm放一起，添加图片往后加代码
