so by the setting the label's opaque to null, the map image and the spot image will go along. . .? that mean the map image will be at the back and the label will be in the front of map image?

As for the layout, I will try to set it as null. . .I hope this will work. . .if this will work, how can I put the component anywhere I want? I am not using net beans or any visual java application. . I am pure hard code.

I found some information on the internet that explain on how to set the location of the label. Thank you for the idea, I will let you know soon if I get this thing right.

You could use something like this in your MapPanel to manage the "spots"

The code works great. . .Thank you so much Ezzaral. . .I would like to ask one last thing. . .please advise me.

I would like to ask if the code is correct, the code will open another window name NewWindow if the point1 label is clicked. This is last problem. . .

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
public void mouseClicked(MouseEvent e) {
            if(e.equals(point1)) {
                NewWindow nw = new Window();
            }
        }
public void mouseClicked(MouseEvent e) {
            if(e.equals(point1)) {
                NewWindow nw = new Window();
            }
        }

You already know which point was clicked, because that point itself is the mouse handler, so all you need to do is create and show the new frame. You can pass whatever information you need from the point label to the frame.

So you mean like this?
Assuming I have 3 frames name:

Point1 p1 = new Point1();
Point2 p2 = new Point2();
Point3 p3 = new Point3();

public void mouseClicked(MouseEvent e) {
Point1 p1 = new Point1();
Point2 p2 = new Point2();
Point3 p3 = new Point3();
}

My apology Sir Ezzaral, I am new to mouse listener and events. . . Hope you understand. . .=)

Each point has its own specific action. . .I need to put If condition to that, I found some codes on the internet and it looks like this:

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
spot1 = new ImageIcon("spot.gif");
point1 = new MapLabel(spot1, "p1");
point1.setBounds(168, 30, spot1.getIconWidth(), spot1.getIconHeight());
spot1 = new ImageIcon("spot.gif");
point1 = new MapLabel(spot1, "p1");
point1.setBounds(168, 30, spot1.getIconWidth(), spot1.getIconHeight());

 Help with Code Tags 
 Java Syntax (Toggle Plain Text) 
public void mouseClicked(MouseEvent e) {
String str = point1.getText();
if(str.equals("p1")) {
NewWindow nw = NewWindow();
}
}
public void mouseClicked(MouseEvent e) {
String str = point1.getText();
if(str.equals("p1")) {
NewWindow nw = NewWindow();
}
}

but it won't work, it won't do any action. . .please, help me with this last action.

How does the action for point1 differ from point2? That is what matters for the mouse handler.

Do you actually have a frame class called NewWindow? Does it make itself visible in it's constructor?
