QDesktopServices not opened jpg files on other's PC

[karankumar1609]

hello all,

i am using QDesktopServices to get open image files.
Image files got open on my PC but unable to open it on other's PC.

QDesktopServices::openUrl(QUrl::fromLocalFile(QString(
                                                                  filePath
                                                                  )
                                                              )
                                          );

QDesktopServices::openUrl(QUrl::fromLocalFile(QString(
                                                                  filePath
                                                                  )
                                                              )
                                          );

To copy to clipboard, switch view to plain text mode 

filePath is normal file path with native seperators:
"C:/a.jpg"

please help if you have any idea about that.
