QPixmap PixEllipseNose;
PixEllipseNose.load(QString::fromUtf8("images/Ellipse1.PNG"));
ui.lblNoseEllipse->setPixmap(PixEllipseNose);

Later some time in program (after timer goes off )I need to display another image

I want to load another image in existing PixEllipseNose but I dont want to set another pixmap in Qlabel .

How to do it???
