How to load an image in Java using toolkit and new URL

I need to use a JPEG image in my Java applet. In my applet class, I define the image name and create an object to ImageBuffer class.

String iname= "image1.jpg";
b = new ImageBuffer(iname,this);

In the ImageBuffer class, I call

Image image = null;
image = Toolkit.getDefaultToolkit().getImage(new URL(applet.getCodeBase(),fileName));

While this does not flag an error and image is not null anymore, it does not initialize image correctly. The height and width are -1. The url of the path however appears to be correct : /C:/Users/..../image1.jpg

How do I correctly load the image? It is in the bin file of my Eclipse project currently.

The height and width are -1.

Use a MediaTracker to monitor the asynchronous loading progress of the image. Alternately use ImageIO to load the image prior to the next code line.

If the image is placed in the correct location, then this would fix it

image = new ImageIcon(Toolkit.getDefaultToolkit().getImage(new URL(applet.getCodeBase(),fileName))).getImage();

If the code returns a NullPointerException it means the image is not placed in the correct directory.
