You can use something like this if you are trying to load an image from a local location.

File file = new File("D:/project/resources/imageA.jpg");
Image image = ImageIO.read(file);

If you are planning to read the image from a URL, use the below code:

URL url = new URL("http://www.google.co.in/images/srpr/logo3w.png");
Image image = ImageIO.read(url);

Please have a look at the below code for better understanding:

package com.stack.overflow.works.main;

import java.awt.Image;
import java.net.URL;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;

/**
 * @author sarath_sivan
 */

public class ImageLoader {

    private ClassLoader classLoader = ClassLoader.getSystemClassLoader();
    private Image image = null;
    private URL url = null;

    /**
     * Loading image from a URL with the help of java.net.URL class.
     */
    public void loadFromURL() {
        image = null;
        try {
            url = new URL("http://www.google.co.in/images/srpr/logo3w.png");
            if (url != null) {
                image = ImageIO.read(url);
            }

        } catch(Exception exception) {
            exception.printStackTrace();
        }
        display(image, "Loading image from URL...");

    }

    /**
     * Loading image from your local hard-drive with getResource().
     * Make sure that your resource folder which contains the image
     * is available in your class path.
     */
    public void loadFromLocalFile() {
        image = null;
        try {
            url = classLoader.getResource("images.jpg");
            if (url != null) {
                image = ImageIO.read(url);
            }

        } catch(Exception exception) {
            exception.printStackTrace();
        }
        display(image, "Loading image from Local File...");
    }



    private void display(Image image, String message) {
        JFrame frame = new JFrame(message);
        frame.setSize(300, 300);
        JLabel label = new JLabel(new ImageIcon(image));
        frame.add(label);
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        ImageLoader imageLoader = new ImageLoader();
        imageLoader.loadFromURL();
        imageLoader.loadFromLocalFile();
    }

}

Output

See here for directions. You can't load an image directly with URL (actually you can, but it is complicated see this question)

Actually you need to do something like this:

ClassLoader loader = ClassLoader.getSystemClassLoader();

if(loader != null) {
   URL url = loader.getResource(name);
}

If you are loading from your classpath you should do something like this

InputSteam is =  this.getClass().getClassLoader().getResourceAsStream("resources/myimage.png")
