      hi @MasterBlade
      to rotate a QPixmap, you have to call transform on it
      that will return a rotated Pixmap, the original is unchanged.

      Q: What's that?
      A: It's blue light.
      Q: What does it do?
      A: It turns blue.

        @MasterBlade

        Use Transformed function

        QPixmap p1("URL");
        QPixmap p2 = p1.transformed(QTransform().rotate(90));
        
        label->setPixmap(p2);
