  • easiest way to put an image here is by using the built in microsoft snipping tool. HIt the windows key and type snipping tool and you should see it pop up in the list. I recommend adding that tool to your quick launch toolbar. Marquee the area of your workspace that you wish to capture then just copy and paste here
