My code is shown below :

bupload.addActionListener(new ActionListener() {

                            public void actionPerformed(ActionEvent evt) {
                                Display.getInstance().openImageGallery(new ActionListener() {

                                    public void actionPerformed(ActionEvent evt) {
                                        try {
                                            if (evt == null) {
                                                return;
                                            }
                                            String path = (String) evt.getSource();

                                            if (path != null) {
ImageIO imageio = ImageIO.getImageIO();
        ByteArrayOutputStream out = new ByteArrayOutputStream();
       
            imageio.save(FileSystemStorage.getInstance().openInputStream(path),
                    out,
                    ImageIO.FORMAT_JPEG,
                    100, 100, 1);
       
        Image im = Image.createImage(out.toByteArray(), 0, out.toByteArray().length);

                                                System.out.println(im);
                                                Image i = Image.createImage(path);
 String img = com.codename1.util.Base64.encode(i.getImage().toString().getBytes());

                                                System.out.println(img);
                                                image.setImage(i);
                                                image.setHeight(50);
                                                image.setWidth(50);

//
                                           String ImageName= path.substring(path.lastIndexOf('/')+1,path.length());
                                            
                                                System.out.println("image..." + " " +ImageName);
                                                System.out.println(path + " " +"Path...");
                                               // Util.cleanup(out);
                                                
                                            }
                                        } catch (IOException ex) {
                                            ex.getMessage();
                                        }
                                    }
                                });
                                
                            }
                        });
