This is an album with a theme image which is also displayed on small devices like an iPhone.The swipe area on the index page is restricted to the theme image, so that the rest of the page can be used for scrolling through the index page. For a slide page, the whole page is used as swipe area.
For an even better usability on small screens, the viewer can enlarge the size of the buttons and if the viewer has troubles reading small letters, he can also enlarge the font-size in the viewer settings (Settings button in the upper right corner). On an iPhone in landscape mode, the toolbar is moved to the bottom, because buttons on the top can't be used on an iPhone in full screen mode.
Variable thumbnail sizes with the Justified Gallery are used, the specified thumbnails size is 600x120 and the Justified-Gallery uses a row heigth of 15% of the screen height.
To view the route in Google Earth, download the map.kml file, open Google Earth in your browser and import the downloaded map.kml file via File / Import KML-KMZ file. On a jAlbum server you will see red crosses instead of the thumbnails, if you do this with a Windows PC. On other servers it works as you can see here.
If you are viewing this on a PC, you can also open the map.kml file in the Google Earth program on your PC, this works also correctly on a jAlbum server.
