Ok, what't the output of

QFileInfo fi(imgPath);
qWarning() << fi.permissions();

QFileInfo fi(imgPath);
qWarning() << fi.permissions();

To copy to clipboard, switch view to plain text mode 

and maybe the jpg is defect, that you may open it with gimp etc. but qt fails. So for debug open the file and save it as png and try to load this in Qt.

jpg are correct and qWarning output is

30583

Sorry if I bother you, but then it must be in your code. Last debug question (with your image):

#include <QtGui>
 
int main(int argc, char **argv)
{
  QApplication app(argc, argv);
 
  QImage image;
  bool result = image.load( "/qt/qtsdk-2009.01/qt/src/3rdparty/libtiff/html/images/smallliz.jpg" );
  qWarning() << result;
 
  QLabel lab;
  lab.setPixmap(QPixmap::fromImage(image));
  lab.show();
 
  return app.exec();
}

#include <QtGui>

int main(int argc, char **argv)
{
  QApplication app(argc, argv);

  QImage image;
  bool result = image.load( "/qt/qtsdk-2009.01/qt/src/3rdparty/libtiff/html/images/smallliz.jpg" );
  qWarning() << result;
    
  QLabel lab;
  lab.setPixmap(QPixmap::fromImage(image));
  lab.show();

  return app.exec();
}

To copy to clipboard, switch view to plain text mode 

don't work? Here on my linux machine it works as expected.
