this is the class who i use to load the images, i use the constructor to call the metod load who load the images in the array percorso.
import java.awt.Component;
import java.awt.Graphics;
import java.awt.Image;
import java.awt.MediaTracker;
import java.awt.Toolkit;
class Track extends Component {
Image[] percorso;
String path;
int n;
int x;
int y;
public Track(String path, int n) {
int i;
this.path = path;
this.n = n;
this.percorso = new Image[n];
for (i = 0; i < n; i++) {
this.percorso[i] = load(path, n, i);
repaint();
}
}
public final Image load(String path, int n, int i) {
Toolkit tool = Toolkit.getDefaultToolkit();
String dot = ".jpg";
path = this.path;
path = path + Integer.toString(i) + dot;
Image img = tool.getImage(path);
try {
MediaTracker track = new MediaTracker(this);
track.addImage(img, 0);
track.waitForID(0);
} catch (InterruptedException e) {
System.out.println("Image not loaded");
}
return (img);
}
@Override
public void paint(Graphics g) {
int i;
g.drawImage(percorso[1], x, y, this);
}
}
This is the class where i create the gui, and i try to add the images to the jlayeredpane, but it’s didn’t work.

i don’t receive any compiler error, i think the error is in the Gui class where i add the images, in the metod track1MouseClicked, i use the JFrom plugin of NetBeans 7.01 for create the frame and company.
I haven’t gone through all of your code, but this will cause problems:
Since you don’t really set the path field here. You’ll want to reverse that line.
More importantly, you’ll want to try to solve your problem in a much smaller simpler program first, a test program that does nothing but read in a bunch of images and displays them, but does nothing else. Then once you have that solved use the code in your larger program. The other benefit is that if your smaller program doesn’t work, you can then post it here as a more reasonably sized program that more folks will be willing to read, analyze, test and correct.
Also, don’t mix AWT components such as
Componentwith Swing components unless absolutely necessary — which isn’t the case with your program.
