1) This breaks down to two questions a) "How to load an image?" b) "How to draw an image to a panel?" 2) The answer to (a) can generally be found in `ImageIO.read(..)` 3) Do you want to use the image as the BG for the panel, or simply show it in a panel? If 'show' - use a `JLabel(ImageIcon(Image))`. — Andrew Thompson, Jan 03 '13 at 01:00

As an aside, what DYM by 'brush'? Is this a 'paint application'? — Andrew Thompson, Jan 03 '13 at 01:06

final Image image = new ImageIcon("C:/images/image.png").getImage();
JPanel panel = new JPanel() {
    @Override
    protected void paintComponent(Graphics g) {
        g.drawImage(imageToPaint, 
            (desired x location), (desired y location), null);
    }
};

-1 do not override `paint` and do not reinvent the wheel. – user1329572 Jan 03 '13 at 02:23
@user1329572 Besides, he said he wants to use the image as "brush". This implies he would like to use a canvas to draw graphics, and using *paint* is the most... canvasy way to display an image. – Name Jan 03 '13 at 03:13

No no no @JesusPlusPlus, paint method is not used for painting such a thingy. Always override `paintComponent()` for such a task. `paint()` is used only when you need to change the state of the `Graphics` object, so that, along with the contents of the said component, it's border as well as children can reciprocate with that changed state of the `Graphics` object. – nIcE cOw Jan 03 '13 at 03:42

@JesusPlusPlus : Happy to know that, KEEP SMILING :-) . I had negated my downvote, though since my daily limit is gone, I am not sure, if did worked or not, though I will again try tomorrow, when the vote meter will be refilled by stackoverflow again :-). Now the answer is providing valuable information with regard to the issue. Just make sure, that while overriding a method, keep the **Access Specifier** same, as much as possible, like it's `protected void paintComponent(Graphics g)` :-) – nIcE cOw Jan 03 '13 at 14:55
