title: not redisplaying an image s
body: <p>Hi everybody  I am a bit of stack here. When I run the program and press the button submit it is supposed to change 4 pictures in every 2 seconds.However it is not redisplaying the images. If anyone can give me a hand it would be great. I am using eclipse and the program is compiling and running. Here is the code.</p>
