            throws ServletException, IOException {
        response.setContentType("text/html;charset=UTF-8");
       
        try {
            //Get image file
            String img = request.getParameter("img");
          
            BufferedInputStream in = new BufferedInputStream(new FileInputStream("path to absolute location of image/"+img));
            //Get image contents
           
            byte[] bytes = new byte[in.available()];
           
            in.read(bytes);
            in.close();
            //Write image contents to response
            response.getOutputStream().write(bytes);
        }catch(IOException ex){
