//        FileImageInputStream fis = new  FileImageInputStream(new File("timg.jpg"));//        FileImageOutputStream fos = new FileImageOutputStream(new File("timg1.jpg"));        FileInputStream fis = new FileInputStream(new File("timg.jpg"));        FileOutputStream fos = new FileOutputStream(new File("timg2.jpg"));        byte[] read = new byte[1024];        int len = 0;        while((len = fis.read(read))!= -1){            fos.write(read,0,len);        }        fis.close();        fos.flush();        fos.close();
