Gscreenshot is a GUI frontend for scrot tool, which lets you take a picture of your desktop or a selected window and save it on your local disk.
Gscreenshot hasn't been under development since 2009, but has been adapted and debianized for SparkyLinux. It is preinstalled (starting from Sparky 4.0) in Sparky editions: LXDE, LXQt, GameOver, Openbox and JWM. Gscreenshot replaced our previous tool called Sparky Screenshot.
sudo apt-get install gscreenshot
