Can't get resource image from file: java.lang.IllegalArgumentException: input == null

Question

projectname
  src
    main
      resources
         Picture.gif
    test
      Test.java

Test.java:

import javax.imageio.ImageIO;
import java.awt.*;
import java.awt.image.BufferedImage;

public class Test {
    public static void main(String[] args) {
        Test test = new Test();
        test.imageLoad();
    }

    public void imageLoad()  {
        try {
            BufferedImage image = ImageIO
                    .read(getClass()
    .getResource("/resources/Picture.gif"));

        }
        catch (Exception e)  {
            e.printStackTrace();
        }
    }
}

running the Test.main gives

java.lang.IllegalArgumentException: input == null!
    at javax.imageio.ImageIO.read(ImageIO.java:1388)

at line

.read(getClass()

Any help is appreciated.
