+	Example of how to combine pyqt and pyexiv2 to display thumbnail data.
+
+	Minimalistic example of how to load and display with pyqt the thumbnail data
+	extracted from an image using the method Image.getThumbnailData().
+	The path to the image file from which the thumbnail data should be extracted
+	should be passed as the only argument of the script.
+
+	It is of course assumed that you have pyqt installed.
