I need help changing the background. It gives me an error everytime I do something with the background. Also I am trying to figured out how to put picture side-by-side. The picture are one after another.

topDestinationListFrame.setTitle("Top 5 Destination List");

topDestinationListFrame.setVisible(true);

}

});

}
