MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
    im = new QPixmap;
    im->load ("im04.jpg");
}
 
MainWindow::~MainWindow()
{
    delete ui;
}
 
void MainWindow::paintEvent (QPaintEvent *){
        QPainter qpainter (this);
        qpainter.drawPixmap (0, 0, *im);
}
/////.h
class MainWindow : public QMainWindow
{
    Q_OBJECT
 
    public:
        explicit MainWindow(QWidget *parent = 0);
        ~MainWindow();
    protected:
            QPixmap *im;
        void paintEvent (QPaintEvent *);
    private:
        Ui::MainWindow *ui;
 
};

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)

Does it work with a png image? If so, you forgot to "include" the jpeg plugin or your path to the image is wrong.

Whenever I load images into GUI, I always register them in the gui widget by using QtDesigner and using QImage to show them in paintEvent and works fine for me at all time.
