Hi All,

demo from website :

Saving a BufferedImage to a file
// BufferedImage to File
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;
import java.io.File;
....
ImageIO.write( aBufferedImage, "jpeg" /* "png" "jpeg" format desired,
no "gif" yet. */, new File ( "snap.jpg" ) /* target */ );

my program with revisions now saves 16 XXX.jpg images :

import java.awt.*;
import java.io.*;
import javax.swing.*;
import javax.imageio.ImageIO;
import java.awt.image.BufferedImage;

public class DiceImage extends JFrame {
  BufferedImage bi = null;
  int C = 0;
  String PixName;

  DiceImage() {
    setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  }
  public void init() {
    try {
      bi = ImageIO.read(new File("images/ImageToDice.jpg"));
    } catch(IOException ioe) {
      ioe.printStackTrace();
      //throw new RuntimeException(ioe);
    }
    setLayout(new FlowLayout());

       if(bi != null) {
      for(int i = 0; i < 4; i++)
        for(int j = 0; j < 4; j++) {
       PixName = "Pix" + C;
       System.out.println(PixName);// review name output
      //screen output
    add(new JLabel(new ImageIcon(bi.getSubimage(i*bi.getWidth()/
4,j*bi.getHeight()/4, bi.getWidth()/4,bi.getHeight()/4))));// image
file output
   try {
        ImageIO.write((bi.getSubimage(i*bi.getWidth()/4,
j*bi.getHeight()/4, bi.getWidth()/4,bi.getHeight()/4)), "jpeg", new
File("images/"+ PixName +
".jpg"));

        C++;
        }
        catch ( IOException e )
         {
          System.out.println( "image missing" );
         }
        }
      pack();
    }
}
  public static void main(String[] args) {
    DiceImage diceImage = new DiceImage();
    diceImage.init();
    diceImage.setVisible(true);
  }
}
