How to save an image in J2ME

This works for me. I have two images (i.png and saved.png) the first is red the second black. The midlet loads the 1st file, then writes over the second (black) so that it appears red.

import java.io.*;
import javax.microedition.io.*;
import javax.microedition.io.file.FileConnection;
import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

public class ImageLoader extends MIDlet
    implements CommandListener, Runnable {
  private Display mDisplay;
  private Form mForm;
 
  public ImageLoader() {
    mForm = new Form("Connecting...");
    mForm.addCommand(new Command("Exit", Command.EXIT, 0));
    mForm.setCommandListener(this);
  }
 
  public void startApp() {
    if (mDisplay == null) mDisplay = Display.getDisplay(this);
    mDisplay.setCurrent(mForm);
   
    // Do network loading in a separate thread.      
    Thread t = new Thread(this);
    t.start();
  }
 
  public void pauseApp() {}

  public void destroyApp(boolean unconditional) {}
 
  public void commandAction(Command c, Displayable s) {
    if (c.getCommandType() == Command.EXIT)
      notifyDestroyed();
  }
 
  public void run() {
    FileConnection fc = null;
    DataInputStream in = null;
    DataOutputStream out = null;
    FileConnection fc1 = null;
   
    try {
      fc = (FileConnection)Connector.open("file:///root1/i.PNG");
      int length = (int)fc.fileSize(); //possible loss of precision may throw error should be handled
      byte[] data = null;
      if (length != -1) {
        data = new byte[length];
        in = new DataInputStream(fc.openInputStream());
        in.readFully(data);
      }
      else {
        int chunkSize = 512;
        int index = 0;
        int readLength = 0;
        in = new DataInputStream(fc.openInputStream());
        data = new byte[chunkSize];
        do {
          if (data.length < index + chunkSize) {
            byte[] newData = new byte[index + chunkSize];
            System.arraycopy(data, 0, newData, 0, data.length);
            data = newData;
          }
          readLength = in.read(data, index, chunkSize);
          index += readLength;
        } while (readLength == chunkSize);
        length = index;
      }
      Image image = Image.createImage(data, 0, length);
      ImageItem imageItem = new ImageItem(null, image, 0, null);
      mForm.append(imageItem);
      mForm.setTitle("Done.");
     
      fc1 = (FileConnection)Connector.open("file:///root1/saved.PNG");

      out = new DataOutputStream(fc1.openOutputStream());
      out.write(data);
    }
    catch (IOException ioe) {
      StringItem stringItem = new StringItem(null, ioe.toString());
      mForm.append(stringItem);
      mForm.setTitle("Done.");
    }
    finally {
      try {
        if (in != null) in.close();
        if (fc != null) fc.close();
      }
      catch (IOException ioe) {}
    }
  }
}
