To fix this issue You draw the image back to itself (?) using a Graphics object derived from the Image itself. Instead store the image to a field, not a local variable, and draw that image within the JPanel's paintComponent method. Most important, have a look at the Swing graphics tutorials
code :
private BufferedImage img;

public void load(String path) throws IOException {
       img = ImageIO.read(new File(path));

protected void paintComponent(Graphics g) {
    if (img != null) {
        g.drawImage(img, 0, 0, null);

I wish this helpful for you In your code you're missing a JFrame or JDialog to contain your JPanel in. Here's an example that I believe does what you're asking for. It loads the same image into a visible window and outputs the dimensions to the console.
code :
public class ImageTool extends JPanel {
    public ImageTool(URL url) {
        ImageIcon icon = new ImageIcon(url);
        JLabel label = new JLabel(icon, JLabel.CENTER);

        System.out.println("Image width: " + icon.getIconWidth());
        System.out.println("Image height: " + icon.getIconHeight());

    public static void main(String[] args) throws MalformedURLException {
        URL url = new URL("http://www.java2s.com/style/logo.png");
        JPanel panel = new ImageTool(url);
        JFrame frame = new JFrame();

wish help you to fix your issue You're question is missing some important information: how are you drawing things on the JPanel? In my opinion, the smart way would be to draw into a BufferedImage, and then simply save the BufferedImage to file using ImageIO.write(...)

I think the issue was by ths following , You should avoid creating new objects everytime you want to display your image, imagine if you change it 5 times, you're creating 5 times an object while you display only one !
Like said in the comments, your best shot would be to create your label when you create your panel, add it to said panel, then simply change the icon of this label when you load your image.
code :
        browseBtn.addActionListener(new ActionListener() {

        public void actionPerformed(ActionEvent e) {
            JFileChooser fc = new JFileChooser();
            int result = fc.showOpenDialog(null);
            if (result == JFileChooser.APPROVE_OPTION) {
                File file = fc.getSelectedFile();
                if (accept(file)) {
                    try {
                        ImageIcon image = new ImageIcon(file.getPath());
                    } catch (Exception ex) {
                        JOptionPane.showMessageDialog(this, "Error reading file !");
                else {
                    JOptionPane.showMessageDialog(this, "Choose png file only !");

        public boolean accept(File file) {
            return file.isDirectory() || file.getAbsolutePath().endsWith(".png");
