Could the QImage image object be the problem?

I think after I load the file using the below code, the image object somehow gets destroyed after the function. What do you think?

Qt Code: 
  1. void MainWindow::open()
  2. {
  3. 	QString fileName = QFileDialog::getOpenFileName(this,tr("Open File"), QDir::currentPath(), tr("Image Files (*.jpg *.jpeg *.bmp *.gif *.png)"));
  4. 	if (!fileName.isEmpty()) {
  5. 		QImage image(fileName);
  6. 		if (image.isNull()) {
  7. 			QMessageBox::critical(this, tr("Image View"), tr("Cannot load %1.").arg(fileName));
  8. 			return;
  9. 		}
  10. 		imageLabel->setPixmap(QPixmap::fromImage(image));
  11. 		scaleFactor = 1.0;
  12. 		closeAction->setEnabled(true);
  13. 		imageLabel->adjustSize();
  14.  
  15. 		imagelabFile.convertToRGBImage(image);		//If loading is ok, create an imagelabfile copy of the QImage
  16. 		brightnessAction->setEnabled(true);
  17. 		QMessageBox::information(this, tr("Successful Conversion"),tr("ImageLab image loaded. Ready for processing."));
  18. 	}
  19. }
