Image processing of sorts but this sure is useful - Snippy

If you havent heard or seen this cool little tool called "Snippy" you gota check it out. It lets you select, copy and paste areas of your screen. The tool takes a print screen and crops it automatically to the area that you select. Snippy is very easy to use and should definitely be something in your tool box.
