How to add an image to a panel?

Question

Java

public class cl{


JLabel enterTheA=new JLabel("Введите число A:");
JTextField numberA=new JTextField();

GridBagLayout gridBagLayout=new GridBagLayout();
    GridBagConstraints c=new GridBagConstraints();

public JPanel  a1 (){
JPanel panel=new JPanel();


 c.anchor = GridBagConstraints.CENTER;
       c.fill   = GridBagConstraints.NONE;
       c.gridheight = 2;
       c.gridwidth  = GridBagConstraints.REMAINDER;
       c.gridx = 0;
       c.gridy = 0;
       c.insets = new Insets(20, 0, 0, 0);
       c.ipadx = 0;
       c.ipady = 0;
       c.weightx = 0.0;
       c.weighty = 0.0;
gridBagLayout.setConstraints(enterTheA, c);
panel.add(enterTheA);

       c.anchor = GridBagConstraints.CENTER;
       c.fill   = GridBagConstraints.NONE;
       c.gridheight = 1;
       c.gridwidth  = GridBagConstraints.REMAINDER;
       c.gridx = 0;
       c.gridy = 2;
       c.insets = new Insets(20, 0, 0, 0);
       c.ipadx = 60;
       c.ipady = 0;
       c.weightx = 0.0;
       c.weighty = 0.0;
        gridBagLayout.setConstraints(numberA, c);
        panel.add(numberA);

return panel;
}}

I need to load a small image after the text field, and place it on the panel (under JTextFiled), throw off the code, it will not be difficult for anyone, it is desirable to use another class to load the image.

Hmm, I have such code in my working project now.
Code for creating a label for a photo:

JLabel photo = new JLabel();
            Icon icon = loadPhoto(editingRecord == null ? "" : editingRecord.getPhotoBase64());
            photo.setIcon(icon);

loadPhoto() method:

private Icon loadPhoto(String base64String) {
        if (isBlank(base64String)) {
            return null;
        }

        byte[] bytes = DatatypeConverter.parseBase64Binary(base64String);
        ByteArrayInputStream bin = new ByteArrayInputStream(bytes);
        try {
            BufferedImage original = ImageIO.read(bin);

            if (original == null || original.getHeight() == 0) {
                return null;
            }

            double factor = 100.0 / original.getHeight();

            int newWidth = new Double(((double) original.getWidth()) * factor).intValue();
            int newHeight = 100;

            BufferedImage resized = new BufferedImage(newWidth, newHeight, original.getType());
            Graphics2D g = resized.createGraphics();
            g.setRenderingHint(RenderingHints.KEY_INTERPOLATION,
                    RenderingHints.VALUE_INTERPOLATION_BILINEAR);
            g.drawImage(original, 0, 0, newWidth, newHeight, 0, 0, original.getWidth(),
                    original.getHeight(), null);
            g.dispose();

            return new ImageIcon(resized);
        } catch (Exception e) {
            logger.error(LogHelper.print("Can't load photo preview for employee", e));
            MessageDialog.showError(this,
                    Global.data().getString("ERROR_READING_EMPLOYEE_PHOTO"),
                    Global.data().getString("ERROR_TITLE"));
        }

        return null;
    }
