Animated gifs get slower... and slower.........

I have subclassed a JPanel to draw animated gifs on, like an image viewer kind of thing. As I redraw different gifs on the panel, they begin to display slower and slower to the point where I have to close the program. How can I prevent this from happening?
class ImagePanel extends JPanel {
Toolkit tk = Toolkit.getDefaultToolkit();
Font f = new Font("Ariel",Font.ITALIC, 24);
JPanel draw = new JPanel(true);
//Constructor
public ImagePanel() {
setContentPane(draw);
setBackground(Color.black);
setForeground(Color.white);
}
//Repaint Method
public void PaintImage(String file) {
try {
img = tk.getImage(file);
mediaTracker = new MediaTracker(this);
mediaTracker.addImage(img, 0);
mediaTracker.waitForID(0);
} catch (InterruptedException e) {
System.out.println("InterruptedException has occurred:"
+ e.getMessage());
return;
}
x1 = img.getWidth(this);
y1 = img.getHeight(this);
x1 = x1/resize;
y1 = y1/resize;
repaint();
}
public void paintComponent(Graphics g) {
int y;
int cl;
super.paintComponent(g);
//~~~~~~~~~~~~~~~This is where we draw the Image
if (img != null) {
g.drawImage(img,0,0,x1,y1,this);
g.dispose();
}
}
