KDE 4.11 (Plasma) : How to change Wallpaper
Yesterday, I installed fresh Linux Mint 16 (KDE). At first, I was confused to change the wallpaper. After few experiments, I figured-out it. In the following way, we can change desktop wallpaper of KDE 4.11: Right click on the desktop (empty space) Click "Folder Settings" "Desktop Settings - Plasma Desktop Shell" window will be opened. "View" option should be selected. Otherwise select "View" option. Select your favorite wallpaper and click "Apply" button.
