请教java高手们，帮我写一个java编写的图片浏览器，功能如下：有自动浏览功能，每隔几秒图片自动翻页。用

//改编的，CopyOfImageViewer.java 打开一个有图片的文件夹就可浏览了。

//MP3播放相关库到:http://www.javazoom.net/javalayer/sources.html 下载

//将下载到的zip文件里的 jl1.0.1.jar 复制到 JDK目录下的 jre/lib/ext/ 目录里即可.

//将 源代码 main 方法里的 playMp3("d:\\bad.mp3");改成自己的地址，换种方法BMP是可以支持的，这里不行暂不讨论。

我搞出来了！效果绝对让你满意！呵呵……（但有一点缺陷：没有背景音乐，因为我暂时还没有弄过有音乐的东西）。
准备工作如下（最好你直接HI我，我把整个项目的代码给你）：
在根目录（src）下放置1.jpg 2.jpg 3.jpg图片。

（0079007的答案我也想运行一下看看效果，但代码是有错误的……不能正确编译）

bmp有难度，其它参考楼上的，自己玩去吧

废物东西..
