Basic painting is done by a Swing components paintComponent method.
The best choice you have is to load the image using the ImageIO API...
BufferedImage image;
public void loadImage() throws IOException {
image = ImageIO.read(...);
// ImageIO can read a image from a file or a URL or a ImageInputStream
}
Then simply paint the image...
protected void paintComponent(Graphics g) {
super.paintComponent(g);
g.drawImage(image, 0, 0, this);
// Now you can continue drawing ontop of it...
g.setColor(Color.RED);
g.drawLine(0, 0, image.getWidth(), image.getHeight());
}
