You might want to have your "main" class implement
runnable then load  the image  in the run() method. Put
a sleep(3000) at the end of run() then call new
Thread(this).start() in your constructor.

Now this is just an idea to get you started. The
implementation details are up to you. For example, you
might need a way to kill the Thread that you started
so you must store it in an instance variable.

Well... I sort of managed to make the image refresh  by doing a loop

and calling this logic every time

" private void refreshImage() {

int i = imageList.getSelectedIndex();
//thread.interrupt();
imageName = (String) imageNames.elementAt(i);
display.setCurrent(genProgress(imageList.getString(i)));
thread = new Thread(this);
thread.start();
}
"
as it refreshes it will not let me do anthing else unless i press
the cancel button.

Also when i tested it on the series 60 emulator everytime I refresh
it asks me if I want to do aconnect asI am all the time calling the
HTTPConnection

c = (HttpConnection) Connector.open(name);
int status = c.getResponseCode();
if (status != 200) {
throw new IOException("HTTP Response Code = " + status);
}

and also in the Series 60 the image  is becoming null when refreshed :
( so Im really stuck...

Is this the line that call the method to reload the
image?
>>display.setCurrent(genProgress(imageList.getString(i)));

If it is you'll have to put that in your run method
otherwise the process will block when it reaches that
line.

Also, I'm not sure if it's available on J2ME but you
might want to look into the MediaTracker class.
