pictures help

[Gamewolf]

Hi

with some help and by looking at tutorials i have managed to create this monstrosity

import javax.swing.*;
import java.awt.*;
import java.awt.event.*;



public class RotateImage extends JPanel {
  int   xk = 0;
  int   yk = 0;

  boolean right, left, up, down;


  // Declare an Image object for us to use.
  Image character, button;

  // Create a constructor method
  public RotateImage() {
    // Load an image to play with.
    character = Toolkit.getDefaultToolkit().getImage("BlobA1.png");
    button = Toolkit.getDefaultToolkit().getImage("earth.png");

    wasd go = new wasd();
    go.start();

    animation blink = new animation();
    blink.start();


    this.setFocusable(true);
    this.addKeyListener(new KeyAdapter() {

      public void keyPressed(KeyEvent e) {
        if (e.getKeyCode() == KeyEvent.VK_RIGHT) {

          			right = true;

        } else if (e.getKeyCode() == KeyEvent.VK_LEFT) {

          			left = true;


        } else if (e.getKeyCode() == KeyEvent.VK_UP) {

          			up = true;

        } else if (e.getKeyCode() == KeyEvent.VK_DOWN) {

          			down = true;

        } else if (e.getKeyCode() == KeyEvent.VK_SPACE) {

          for (int hopp = 1; hopp <= 20; hopp++) {

            yk = yk - 1;

            RotateImage.this.repaint();

            try {
              Thread.sleep(50);
            } catch (InterruptedException f) {
            }
          }

        }
      }

      public void keyReleased(KeyEvent e) {

      	if(e.getKeyCode()==KeyEvent.VK_RIGHT)
      		right = false;

      	if(e.getKeyCode()==KeyEvent.VK_LEFT)
      		left = false;

      	if(e.getKeyCode()==KeyEvent.VK_UP)
      		up = false;

      	if(e.getKeyCode()==KeyEvent.VK_DOWN)
      		down = false;

      }

    });


  }

  class animation extends Thread
  {
  	public void run()
  	{
  		while(true)
  		{
  			character = Toolkit.getDefaultToolkit().getImage("BlobA1.png");

  			try {
              Thread.sleep(2000);
            } catch (InterruptedException f) {
            }

            character = Toolkit.getDefaultToolkit().getImage("BlobA2.png");

            try {
              Thread.sleep(2000);
            } catch (InterruptedException f) {
            }



  		}

  	}

  }

  class wasd extends Thread
  {
  	public void run()
  	{

		while(true)
  		{
  			if(right==true)
  				xk = xk + 1;

  			if(left==true)
  				xk = xk - 1;

  			if(up==true)
  				yk = yk - 1;

  			if(down==true)
  				yk = yk + 1;

  			repaint();

  			try{
				Thread.sleep(17);}
			catch(InterruptedException f){
			}


  		}

  	}

  }

  public void paintComponent(Graphics g) {
  	super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g; // Create a Java2D version of g.
    g2d.translate(xk, yk); // Translate the center of our coordinates.
    g2d.rotate(0); // Rotate the image by 1 radian.
    g2d.drawImage(character, xk, yk, this);

  }


  public static void main(String[] arg) {

    final JFrame frame = new JFrame("RotateImage");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(1280, 720);

    RotateImage panel = new RotateImage();
    frame.setContentPane(panel);
    frame.setVisible(true);
    frame.setResizable(false);

  }
}

it is just a moveable blob which blinks, now however i want to get more pictures into the program, how do i do that? when i made an attempt i got other pictures into panel but they moved with the blob. i want them to be independant, any ideas?

ok i solved my problem, however i am now facing a new one. by using the rectangle function i want to have a kind of unit collision, how do i get the width and height from my picture?
