#include <QDesktopServices>
#include <QStringList>
#include <QString>
#include <QList>
#include <QDir>
#include <QFileInfoList>
#include <QFileInfo>
 
QList<QString>   pictures;

Source

Search for the device's picture folder:

// Search device picture location directory
QDir picturesDir;
picturesDir.setPath(QDesktopServices::storageLocation
(QDesktopServices::PicturesLocation));

Search for pictures in the device's picture folder:

// Search files from the directory
QFileInfoList fileList = picturesDir.entryInfoList(QStringList(), 
QDir::Files | QDir::Dirs, QDir::Time);
for (int i = 0; i < fileList.size(); ++i)
    {
    QFileInfo fileInfo = fileList.at(i);
 
    if (fileInfo.isHidden())
        continue;
 
    #ifndef Q_OS_SYMBIAN
    if (fileInfo.filePath().length()>0 && 
    fileInfo.filePath().right(1) == ".")
        continue;
 
    if (fileInfo.filePath().length()>1 && 
    fileInfo.filePath().right(2) == "..")
        continue;
    #endif
 
    // File found
    if (fileInfo.isFile())
        {
        if (fileInfo.filePath().indexOf(QString(".jpeg")
        ,0,Qt::CaseInsensitive)>0 ||
                fileInfo.filePath().indexOf(QString(".jpg")
                ,0,Qt::CaseInsensitive)>0)
            {
            // Store picture path to array
            pictures.append(fileInfo.filePath());
            }
        }
    // Direcotry found        
    else if (fileInfo.isDir())
        {
        // TODO: we do not handle sub-directoires
        }
    }

Open the first picture into the device's built-in picture gallery application:

QDesktopServices::openUrl(QUrl("file:///" + pictures[0]));

Open an HTML page into the device's built-in HTML browser application:

QDesktopServices::openUrl(QUrl("http://www.forum.nokia.com"));
