When we apply image icon to any component like button, label or panel, it not apply properly because of size of that image. We can resize that image icon in two ways.

1. first way: Image img = myIcon2.getImage(); Image newimg = img.getScaledInstance(230, 310, java.awt.Image.SCALE_SMOOTH);
   newIcon = new ImageIcon(newimg);

2. second way:

   Image img = myIcon2.getImage(); BufferedImage bi = new BufferedImage(img.getWidth(null), img.getHeight(null), BufferedImage.TYPE_INT_ARGB);
   newIcon = new ImageIcon(bi);
