SnapIt

From Digeus:

Capture anything you see on your PC screen. Don't waste time cropping your captures. Take a "snapshot" of anything exactly what you need, with just a click. Irreplaceable tool for designers, office workers, business people, analysts, technical writers who have to describe interfaces, menus, buttons. Using SnapIt takes just three simple steps: Start the program (click on the program's icon). It appears minimized in a system tray. Click PrtScr (Print Screen) button and select with mouse what you need to capture on the screen. After selecting the region is automatically copied to the clipboard. Save a snapshot from the clipboard with any way you like. Use the Properties menu to define the hot key you want to press to take your screenshots. And the most powerful feature of SnapIt is the following. In menu Properties you may switch on "Auto save images" option. It means that every time you capture image on your PC screen you don't need to save it! It will be saved automatically in the selected folder with selected image type. It is a very convenient feature for web designers who surf the Internet for new graphic ideas and want to save them in their local collection with one click.
