Jing is a great tool that allows you to instantly capture images and videos—then share them with anyone. It allows you to send your screenshots to your favorite sites eg Facebook, Twitter etc and you can also save the screenshots to your PC.
You initiate a capture by clicking Jing's happy always-ready "sun" icon seen in the picture below:
You can capture a window, pane, or region. After selecting a window or region, Jing will record everything that appears in that area.
Point to things with your mouse, scroll, flip through photos, click around in a website or application... Jing captures it, though Jing videos are limited to 5 minutes for instant, focused communication.
