       int type = oriImage.getType();
       int width = 500;
       int height = 500;
       BufferedImage bImage = new BufferedImage(width, height, type);
       Graphics2D g = bImage.createGraphics();
       g.setComposite(AlphaComposite.Src);
       g.drawImage(image, 0, 0, width, height, null);
       File resizedImage = new File(despic);
       ImageIO.write(bImage, "jpg", resizedImage);
       g.dispose();
      }
     catch (IOException ex) {
