Here is what you would do... you need to have another image that is defined as the current Image that is being displayed. Then you need to have the thread switch the image being displayed, repaint the applet, and sleep for 500 milliseconds.

Also, it is a good idea to override the start() and stop() methods of the applet to start and stop the thread... if you don't do this the thread continues to run, wasting resources even when the applet is not displaying.

Here is your updated code...
