	Image img = getToolkit().getImage("img\\mapa-geo.png");

	MediaTracker mt = new MediaTracker(this);
	mt.addImage(img, 1);
	try {
		mt.waitForAll();
	} catch (Exception e) {
		System.out.println("Image not found.");
	}
	image = new BufferedImage(img.getWidth(this), img.getHeight(this),
			BufferedImage.TYPE_INT_ARGB);
	Graphics2D g2 = image.createGraphics();
	g2.drawImage(img, 0, 0, this);
}

public void paintComponent(Graphics g) {
	super.paintComponent(g);
	Graphics2D g2D = (Graphics2D) g;
	g2D.drawImage(image, x, y, this);
