           Socket incoming=s.accept();
           try
            OutputStream os=incoming.getOutputStream();
            for (int i = 0;i<100 ; i++)
                img = robot.createScreenCapture(rect); 
            //repaint();
                ImageIO.write(img,"jpg",os);
                if(img==null)
                 System.out.println("NULL");

It's been a while, but I know you can write a series of images to a file, then later read back that series of images. Why don't you work on doing this with file i/o first (easier to debug, and you can examine the file with standard image viewers), before sprinkling sockets on it?
