picBox enables you to share text, images, screen snips, and screen captures effortlessly and seamlessly to anyone on the internet.
To start a screen capture, press the printscreen button and click and drag to select an area, release your mouse, and it will upload the screenshot for you, returning a web address to your clipboard and browser for quick pastes into chats, e-mails, and even social networks. At any point while in capture screen mode, press the Esc key or right-click on your mouse if you'd like to cancel image capture.
