Am trying to set a background image for my frame but it does not work. I tried this link:

The code:

setConten         


        

Answer 1

I've an inkling the problem may lie with

setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("/Images/about.png")))));

Try removing the leading slash in the file path, as this may be interpreted differently based on the OS:

setContentPane(new JLabel(new ImageIcon(ImageIO.read(new File("Images/about.png")))));
