class Example(QMainWindow):

    def __init__(self, parent=None):
        super(Example, self).__init__(parent)

        self.setWindowTitle("Main Window")
        self.resize(200, 100)
        self.scrollArea = QScrollArea()

        self.base = QLabel()
        self.base.setPixmap(QPixmap("aaa.png"))
        self.scrollArea.setWidget(self.base)
        self.setCentralWidget(self.scrollArea)

def main():

    app = QApplication(sys.argv)
    win = Example()
    win.show()
    sys.exit(app.exec_())

if __name__ == '__main__':
    main()

scrollAreaはsetWidgetしかないから
複数Widgetを入れるには

        self.scrollArea = QScrollArea()
        self.base = QWidget()
        self.layout = QHBoxLayout(self.base)
        #self.layout = QHBoxLayout()
        #self.base.setLayout(self.layout) #という書き方もアリ
        self.label1 = QLabel()
        self.label1.setPixmap(QPixmap("aaa.png"))
        self.label2 = QLabel()
        self.label2.setPixmap(QPixmap("bbb.png"))
        self.layout.addWidget(self.label1)
        self.layout.addWidget(self.label2)
        self.scrollArea.setWidget(self.base)
        self.setCentralWidget(self.scrollArea)

こんなかんじ？
