Put the file logo.pngin the same package as the class calling it

ProjectRoot
         src
             MyClass.java
             logo.png

and use

ImageIcon icon = new ImageIcon(getClass().getResource("logo.png"));
setIconImage(icon.getImage());

For more information, see Exclude Image Image Icon .
