Dentro de seu JFrame, coloque um JDesktopPane.

Dentro do JDesktopPane coloque um JLabel bem grande (do tamanho que vai querer que sua imagem ocupe). Ai, no “post-init code” deste JLabel, coloque o seguinte código:

javax.swing.ImageIcon icon = new javax.swing.ImageIcon("./caminho/imagem.jpg"); java.awt.Image img = icon.getImage().getScaledInstance(800, 600, java.awt.Image.SCALE_AREA_AVERAGING); meuJLabel.setIcon(new javax.swing.ImageIcon(img));

Isso deve resolver!
