  background-position: center;
}

Use

Images can be:

• SetWallpaperNow: Applied as wallpaper now
• SetAsFavourite: Added to favourite to shuffle and apply whenever required
• SetAsDefault: Set a default wallpaper to revert to easily

by right clicking any image on Nautilus

• To shuffle and apply an image, run update-wallpaper
• To revert to the default one, run set-default-wallpaper

Setting custom key-bindings:

Custom key bindings comes very handy whenever using those commands. You can set custom bindings with custom scripts easily. For help, see this. (For example I have set Ctrl+Alt+s for update-wallpaper and Ctrl+Alt+d for set-default-wallpaper)
