switching images

I take it your asking for help on the entire applet not just the switching images part. If so, try going through the tutorials on this site so you understand the construction of an applet.

As for the actual image switching bit you need something like this in your applet...

import java.awt.*;

import java.applet.*;

public class MyApplet extends Applet {

Image img1;

Image img2;

Image shownImage;

public void init() {

// Load in the images

img1 = Toolkit.getDefaultToolkit().getImage(...URL of image...);

img2 = Toolkit.getDefaultToolkit().getImage(...URL of second image...);

try {

// Wait for the images to be loaded

MediaTracker imgTracker = new MediaTracker(this);

imgTracker.addImage(img1, 0);

imgTracker.addImage(img2, 0);

imgTracker.waitForID(0);

} catch (Exception e) {

}

shownImage = img1;

}

public void paint(Graphics g) {

// Draws the currentl selected image

g.drawImage(shownImage, 0, 0, this);

}

// Method which does the image switching

public void methodTriggeredBySomeEvent(Event e) {

if(shownImage==img1) {

shownImage = img2;

} else {

shownImage = img1;

}

}

}

I havn't tested this and its not complete. You will have to put in the code which triggers the image switching bit.
