[KamilR]

Hi, I have a JPanel, i need draw a picture into this panel, but i need set width and height of this panel same like width and height of pictures, how should i do?

If you can get the dimension of your picture, then you can also do it....

Initialize the GUI.
Get the picture's dimension,
Resize the frame.
Resize the panel. and other components if affected.
Draw the picture,
update the GUI.

The JPanel will report its preferredSize to its parent container. You can use the setPreferredSize method _or_ override the getPreferredSize method to set the preferredSize of the panel. If the panel is added to a container whose layout manager respects the preferredSize of its children, ie, tries to display the children at their preferredSize, the panel should appear at the same size as the image.
In java this could look something like this:

class Pseudo extends JPanel {
    BufferedImage image;
    Dimension size = new Dimension();

    Pseudo(BufferedImage image) {
        this.image = image;
        size.setSize(image.getWidth(), image.getHeight());
        // Option 1: use [i]setPreferredSize[/i] method.
        setPreferredSize(new Dimension(image.getWidth(), image.getHeight()));
    }

    protected void paintComponent(Graphics g) {
        super.paintComponent(g);  // just in case
        g.drawImage(image,0,0,this);
    }

    /** Option 2: override [i]getPreferredSize[/i] method. */
    public Dimension getPreferredSize() {
        return size;
    }
}
