getCodeBase() file location ?

[cryptfilter]

hi, getting into applets using netbeans 7.0.1 with glashfish 3.1.

with this code.

import java.awt.*;
import java.applet.Applet;
public class testMyApplet extends Applet
{
@Override
public void paint(Graphics g)
{
Image img = getImage ( getCodeBase(),"testCrossRoad.png");
// x y width height
g.drawImage(img, 50, 50, 300, 300 , this);
}
}

my question is, where should i save the "testCrossRoad.png" file in the code folder. i currently have it in project folder/web/images.
will using the command getImage ( getCodeBase(),"testCrossRoad.png"); access the file. or am i not setting the file location correctly
