Hello I am trying to draw an Image but it never works. I also tryed to load the image in Different ways but allways the same. But there is noch warning so something like that showing up. But when I put it as an Icon in an JLable it works.

But why not just use `setIcon`? Why do you need to paint the image yourself? — MadProgrammer, May 19 '15 at 00:17
because I later have more pics and thought that would be better but maybe I am wrong — Simon Schulz, May 19 '15 at 07:08
If all you want to do is show them, `JLabel` is fine, you can use `setIcon` to change the image been displayed as well, all automagically — MadProgrammer, May 19 '15 at 07:10
do you know how they make it in big games with many graphics??? — Simon Schulz, May 19 '15 at 07:10
Maybe something like [this](http://stackoverflow.com/questions/13022754/java-bouncing-ball/13022788#13022788) or [this](http://stackoverflow.com/questions/23417786/rotating-multiple-images-causing-flickering-java-graphics2d/23419824#23419824)? — MadProgrammer, May 19 '15 at 07:13

final BufferedImage image = ImageIO.read(new File("C:\image.png"));

Confused are you trying to draw to a JPanel/JFrame?

https://docs.oracle.com/javase/tutorial/2d/images/

final BufferedImage image = ImageIO.read(new File("C:\image.png"));
GamePanel gamePanel;

 JPanel pane = new JPanel() {
        @Override
        protected void paintComponent(Graphics g) {
            super.paintComponent(g);
            g.drawImage(image, 0, 0, null);
        }
    };


    gamePanel(or screen).add(pane);
}

I add the Screen(Label) to an JPanel and Later the JPanel to an JFrame if that is your question – Simon Schulz May 18 '15 at 23:50
Lol dont use "Toolkit.getDefaultToolkit().createImage("monster.jpg");" to draw an image onto screen.. Use BufferedImage preferably – 0x2B May 18 '15 at 23:56
