In my opinion it would be fantastic, if an option would be available to redirect a browser automatically to the mobile version if Flash is not installed.
Of course, this should only happen when the visitor is not a spider / crawler.
The mobile version looks much better than the HTML gallery. If it would be possible to define a maximum width / height in the admin settings for the mobile gallery being displayed on a desktop computer, the 'viewing experience' will be as good as on a tablet / phone.
Merry Christmas!
