Lighting in each picture depends on where at the moment is the sun. The time of year is also taken into account: for example, the winter light in the image will not be as bright as summer. The service supports the wallpaper in resolutions up to 5K - and those already in the catalog.
If you do not like the wallpaper, which is on the site, you can create your own. To do this through the appropriate section of the downloaded pictures with filled EXIF-data the time and location. You can specify which picture will be displayed on the screen during the day, and which - at night.
