Do you mean the Frame Icon?

this.setIconImage(new ImageIcon(getClass().getResource("your.gif"))

No create a label and pass an instance of Image to it's constructor. So you create an Image (which is an abstract class) by means of the ImageIcon class (which extends from the Image class) and pass it to the constructor of the JLabel class. And voila you have a JLabel that contains an image. Now all you need to do is add the JLabel to a sort of container.

The this.setIconImage changes the icon displayed at the left top of the frame. IOW the application icon and you do not want that.

Try this ....

// Fetch icon
Icon icon = new ImageIcon("icon.gif");
   
 // Create a label with text and an icon; the icon appears to the left    of the text..
JLabel label = new JLabel("Text Label", icon, JLabel.CENTER);
   
// Create a label with only an icon
label = new JLabel(icon);

// Add an icon to an existing label
label.setIcon(icon);
