By default, SimpleViewer will display the Flash Player version of the gallery if Adobe Flash Player is available in the user's browser or device. Otherwise, SimpleViewer will display the Mobile Player version of the gallery.
(It is not possible to have the Flash Player version of the gallery used on mobile devices which do not support Adobe Flash Player.)
The only way to override this behavior is to use the 'Use Flash' checkbox in the gallery settings window.
If 'Use Flash' is selected, then the default behavior (above) will be used.
If 'Use Flash' is deselected, then SimpleViewer will use the Mobile Player in all browsers and on all devices, regardless of whether or not Adobe Flash Player is supported.
