java - JLabel and icon mac issue -

so remember 2 years ago had issue displaying icon on label on mac.

i've tried again year whilst working on project , still have same issue. check code works on different computer? either mac or windows know code works , if has idea why doesn't work on mine let me know!

all happens frame appears text , buttons no background image.

public class memoryroom extends jpanel { /** background image of menu screen */ private image bg = new imageicon("memoryroom.jpg").getimage();  /** jframe used in entire game */ protected jframe app;   public memoryroom(jframe app) {     app.setdefaultcloseoperation(jframe.exit_on_close);     app.setvisible(true);     app.setsize(1150, 680);     this.app = app;     initialize();     app.repaint(); }  protected void initialize() {     //final jpanel menuscreenpanel = new jpanel();     setvisible(true);     setsize(1150, 680);     setlayout(null);      jlabel lblselectgame = new jlabel("please select game wish play:");     lblselectgame.setbounds(320, 180, 600, 50);     add(lblselectgame);     lblselectgame.setfont(new font("dialog", font.bold, 24));     lblselectgame.setforeground(color.white);      jbutton btnsnakesandladders = new jbutton("snakes , ladders");     btnsnakesandladders.setbounds(370, 250, 200, 45);     add(btnsnakesandladders);      jbutton btndanscrazytic = new jbutton("dan's crazy tic tac toe");     btndanscrazytic.setbounds(590, 250, 200, 45);     add(btndanscrazytic);     btndanscrazytic.addactionlistener(new actionlistener() {         public void actionperformed(actionevent tictactoeevent) {                 setvisible(false);         }     });     btnsnakesandladders.addactionlistener(new actionlistener() {         public void actionperformed(actionevent snakesandladdersevent) {                 setvisible(false);         }     });      app.getcontentpane().add(this); }  @override public void paintcomponent(graphics g) {     super.paintcomponent(g);     g.drawimage(bg, 0, 0, 1150, 680, this); }  public static void main (string args []){     new memoryroom(new jframe()); }  }
