下面是两种显示图片的简单方法：

package org.bruce.vertices.asist.experiments;

import java.awt.BorderLayout;
import java.net.URL;

import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;

public class ShowImage extends JFrame {
	private static final long serialVersionUID = -6736454674070258636L;

	/**
	 * @param args
	 */
	public ShowImage() {
		JPanel panel = new JPanel(new BorderLayout());
		JPanel panel2 = new JPanel(new BorderLayout());
		JPanel panel3 = new JPanel(new BorderLayout());

		String urlString = "D://MyEclipse 6.0//新建文件夹//Exam//bin//images//winter.jpg";
		JLabel label = new JLabel(new ImageIcon(urlString));

		URL url = getClass().getResource("/images/orz2.jpg");
		JLabel label2 = new JLabel(new ImageIcon(url));

		URL url2 = getClass().getResource("/images/orz.jpg");
		JLabel label3 = new JLabel(new ImageIcon(url2));

		panel.add(label, BorderLayout.CENTER);
		panel2.add(label2, BorderLayout.CENTER);
		panel3.add(label3, BorderLayout.CENTER);

		this.getContentPane().setLayout(new BorderLayout());
		this.getContentPane().add(panel, BorderLayout.CENTER);
		this.getContentPane().add(panel2, BorderLayout.SOUTH);
		this.getContentPane().add(panel3, BorderLayout.EAST);

		this.setSize(400, 300);
		this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
		this.setTitle("显示图像");
		this.setVisible(true);
	}

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		new ShowImage();
	}

}
