Useful tip: Replace gnome-screenshot with screenie
I stumbled onto this, today: How To: Replace ScreenCapture with KSnapshot.
I was pleased to discover that this little tip works just as well with my own screenie and gnome-screenshot, if you are working in Gnome:
[root][mark] # cd /usr/bin/
[root][bin] # mv gnome-screenshot gnome-screenshot.old
[root][bin] # ln -s /usr/local/bin/screenie gnome-screenshot
