The Fastest Way To Do Customizable Screenshot
LightShot is a screen capture program for Windows that supports uploading and online editing of images.
LightShot takes control of the PrintScreen key, allowing you to select the region you want captured. If desired once you have selected a region, there is a full-screen button you can choose to capture the entire screen.
As with other screen capture packages, LightShot lets you copy snapshots to the clipboard or save them to disk (LightShot supports PNG, JPEG and BMP formats).
Other features allow you to upload your captured image to the prntscr.com service, and you can even edit it online via the Pixlr editor.
