Try This

Dont forget to change name of the image file.

import java.awt.*;

import java.io.*;

import javax.swing.*;

public class TextImage {

public static void main(String args[])

{

JFrame frm = new JFrame("Text Demo.");

MyText txt = new MyText();

frm.add(new JScrollPane(txt));

frm.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

frm.pack();

frm.setVisible(true);

}

}

class MyText extends JTextArea

{

ImageIcon img = new ImageIcon("Unicorn.jpg");

public MyText()

{

super(20,70);

}

public boolean isOpaque()

{

return false;

}

public void paint(Graphics g)

{

img.paintIcon(this , g, 0,0);

super.paint(g);

}

}
