请给我的JAVA程序添加一个自动播放图片功能

Question

我写了一个JAVA窗口代码，请给这个这段代码添加一个功能，让它能自动播放电脑内任何一个文件夹里的所有图片，谢谢

public class Main {

/**

* the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
final Frame f = new Frame("毕业纪念册");// 标题
final JLabel lbl = new JLabel();
f.setSize(600, 400);// 对话框大小
f.setLocation(100, 100);// 对话框初始位置
f.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {
System.exit(0);
}
});
MenuBar mb = new MenuBar();
Menu m1 = new Menu("photolist");
Menu m2 = new Menu("video栏");
MenuItem mi1 = new MenuItem("photo1");
MenuItem mi2 = new MenuItem("open");
mi2.addActionListener(new ActionListener() { // 打开文件夹

public void actionPerformed(ActionEvent e) {
FileDialog fd = new FileDialog(f, "photo open",
FileDialog.LOAD);
fd.show();

String fileName = fd.getDirectory() + fd.getFile();
Icon icon = new ImageIcon(fileName,"");
lbl.setIcon(icon);
}
});
MenuItem mi3 = new MenuItem("photo3");
MenuItem mi4 = new MenuItem("photo4");
MenuItem mi5 = new MenuItem("video1");
MenuItem mi6 = new MenuItem("video2");
m1.add(mi1);
m1.add(mi2);
m1.add(mi3);
m1.add(mi4);
m2.add(mi5);
m2.add(mi6);
mb.add(m1);
mb.add(m2);
f.setMenuBar(mb);
f.add(lbl);
f.show();
}

}
做的效果 就是每隔几秒 换一张。我想做个毕业纪念册，最好能播放VIDEO，呵呵，大大们看怎么设计啦，最符合要求的加分，能加多少加多少
