How do you take HorseIsle screenshots?

Press "Print Screen SysRq" on your keyboard, it should be near the scroll lock and f12. That will take a copy of your whole screen at the moment you press it. In paint (or any art/photo editing program) you can crop it to just include the horse isle game.

Also, if you have Windows Vista or Windows 7, there is a tool called the Snipping Tool that is used to take screenshots. Go to start > all programs > accesories > snipping tool, or go to the start menu and search for it. The Snipping Tool will allow you to take screenshots of a certain area on the screen, and you select this by dragging a rectangle around the area you'd like to take the screenshot of. It will then pop up in another window, where you can save it, copy it, send it to others, edit it etc.
