    public GUI()

        frame = new JFrame("Chess");
        squares = new JPanel[8][8];
        frame.setSize(500, 500);
        frame.setLayout(new GridLayout(8, 8));
        frame.setVisible(true);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        for (int i = 0; i < 8; i++) {
            for (int j = 0; j < 8; j++) {
                squares[i][j] = new JPanel();

                if ((i + j) % 2 == 0) {
                    squares[i][j].setBackground(Color.white);
                } else {
                    squares[i][j].setBackground(Color.orange);

        ImageIcon rookW = new ImageIcon("/images/rookW.png");
        ImageIcon queenW = new ImageIcon("/images/queenW.png");
        ImageIcon kingW = new ImageIcon("/images/kingW.png");

        ImageIcon pawnB = new ImageIcon("/images/pawnB.png");
        ImageIcon knightB = new ImageIcon("/images/knightB.png");
        ImageIcon bishopB = new ImageIcon("/images/bishopB.png");
        ImageIcon rookB = new ImageIcon("/images/rookB.png");
        ImageIcon queenB = new ImageIcon("/images/queenB.png");
        ImageIcon kingB = new ImageIcon("/images/kingB.png");

        squares[0][0].add(new JLabel(rookW));
        squares[1][0].add(new JLabel(knightW));
        squares[2][0].add(new JLabel(bishopW));
        squares[3][0].add(new JLabel(queenW));
        squares[4][0].add(new JLabel(kingW));
        squares[5][0].add(new JLabel(bishopW));
        squares[6][0].add(new JLabel(knightW));
        squares[7][0].add(new JLabel(rookW));

        squares[0][7].add(new JLabel(rookB));
        squares[1][7].add(new JLabel(knightB));
        squares[2][7].add(new JLabel(bishopB));
        squares[3][7].add(new JLabel(queenB));
        squares[4][7].add(new JLabel(kingB));
        squares[5][7].add(new JLabel(bishopB));
        squares[6][7].add(new JLabel(knightB));
        squares[7][7].add(new JLabel(rookB));

        for (int i = 0; i < 8; i++)
        {
            squares[i][1].add(new JLabel (pawnW));
            squares[i][6].add(new JLabel (pawnB));
        }

    }

}

I'm not able to get the icons to display. I've looked through multiple tutorials on this as well as looked at others' code.

I tried three different ways:

ImageIcon pawnW = new ImageIcon(getClass().getResource("/images/pawnW.png"));
ImageIcon knightW = new ImageIcon("images/knightW.png");
ImageIcon bishopW = new ImageIcon("/images/bishopW.png");

How are you compiling and building your code? With intellij? - Sotirios Delimanolis

Have you tried with the full path? e.g. c:/users/collin/ ... - ahmedalkaff

@ahmedalkaff The Class#getResource(..) method expects a path relative to the classpath. - Sotirios Delimanolis

The first should work, unless the images was never built into the bin. Check the bin or its equivalent in Intellij (I have no clue what that is) and see if the images esta ahí. - Paul Samsotha

It's likely that intellij does not include the src directory within it's class path for running application. Have you compiled and built the project? Do you have a Jar file? If you do, unzip and see what's included... - MadProgrammer

Antes cualquier cosa, as a side note, setVisible debería ser el pasado thing you do después de adding all components

Also check the below

Funciona bien para mí usando getClass().getResource()

 String path = "/images/stackoverflow2.png";

 ImageIcon pawnW = new ImageIcon(getClass().getResource(path));

Check all below, then when correct it, constrúyelo, luego ejecútelo.
