Texture:illegal image size problem with loading texture

Question

i have used the method of loading an texture into a scene as shown in chapter 7 of java 3d tutorials. My image size is of the power 2. But why am i still getting the illegal image size error, pleeeeaaaase help, i will be greatful for any suggestions thank you. i have pasted the source code for the method of loading a texture below
Thank you
BranchGroup scene= new BranchGroup();
QuadArray plane = new QuadArray(4,GeometryArray.COORDINATES|GeometryArray.TEXTURE_COORDINATE_2);
Point3f p = new Point3f();
p.set(-1.0f,1.0f,0.0f);
plane.setCoordinate(0,p);
p.set(-1.0f,-1.0f,0.0f);
plane.setCoordinate(1,p);
p.set(1.0f,-1.0f,0.0f);
plane.setCoordinate(2,p);
p.set(1.0f,1.0f,0.0f);
plane.setCoordinate(3,p);
TexCoord2f q = new TexCoord2f();
q.set(0.0f,1.0f);
plane.setTextureCoordinate(0,0,q);
q.set(0.0f,0.0f);
plane.setTextureCoordinate(0,1,q);
q.set(1.0f,0.0f);
plane.setTextureCoordinate(0,2,q);
q.set(1.0f,1.0f);
plane.setTextureCoordinate(0,3,q);
TextureLoader loader = new TextureLoader("C:\\Documents and Settings\\Ozcan\\Desktop\\Java 3d\\examples\\texture\\brick.GIF",this);
ImageComponent2D image = loader.getImage();
Texture2D texture = new Texture2D();
texture.setImage(0,image);
Appearance appearance = new Appearance();
appearance.setTexture(texture);
Shape3D shape = new Shape3D(plane,appearance);
scene.addChild(shape);
return scene;

GridBagLayout will make arrangements to display the JPanel at the size its layout manager says that it needs. To help the JPanels layout manager we can let it know that we need extra space to show the rendered image.
class tt extends JPanel{
    Image pic1;
    tt(){
    public void paintComponent(Graphics comp){
    public Dimension getPreferredSize() {
        return new Dimension(pic1.getWidth(this), pic1.getHeight(this));
}
