Actually there is a very simple solution for this problem. There are two things you should modify:

1. Set the scaled content to true (mentioned above)

   QLabel lblImage;
   
   lblImage->setPixmap( QPixmap( "big_image.jpg" ) );
   
   lblImage->setScaledContents( true );
   
   lblImage->setSizePolicy( QSizePolicy::Ignored, QSizePolicy::Ignored );
   

If the lblImage is resizing automatically, the image will stretch to the size of the label.
