Pictures are pre-resized to fit the N9 display. From landscape & city shots, cars, animals, celebrities to abstract art you find pretty much all kind of categories.

There are two ways to get those wallpapers on your phone:
a. Download wallpapers on your computer and transfer them to your N9 (mass-storage mode, Bluetooth). I recommend to transfer them into the Pictures folder.
b. Download wallpapers straight on your phone by visiting Nokia N9 wallpapers with Nokia browser (see pictures below).
- Choose a wallpaper by clicking on it
- Click&hold a resolution (usually 480x854)
- Save to Gallery
- Enter a name for your wallpaper
- Go to application menu and open the downloaded wallpaper in Gallery. There you can select Set as wallpaper
- Enjoy your new wallpaper!
