    int size =  800;
    private BufferedImage sc ;
    JLabel label ;

    public Prove()
    {       
        JFrame frame = new JFrame();
        frame.getContentPane().add(this);
        frame.setSize(2*size, size);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setVisible(true);

        try{ sc = ImageIO.read(new File("Images/ser.jpg"));

        g.setColor(Color.GRAY);
        g.fillRect(0,0, getWidth(),getHeight());        //prapavijen 

        Graphics2D g2 = (Graphics2D)g;

        paintScore(g2);
    }

    public void paintScore(Graphics g2)
    {

        if(sc != null)
        {
            Graphics gi = sc.createGraphics();
            gi.setFont(new Font("Times New Roman", Font.BOLD, 20));
            String r = counter+"";
            gi.drawString(r, 20, 20);
            counter ++;
            this.repaint();
            try{Thread.sleep(500);}

    public static void main(String[] args)
    {
        new Prove();

    }

There is no reason to draw the text directly on the image. Simply draw the image to the component Graphics instance then draw the string to the same Graphics.
