Screenshot Captor is featured in PC World' just posted "Show, don't tell: 6 great tools for capturing, annotating, and sharing screenshots":http://www.pcworld.com/ar...-sharing-screenshots.html
Compared to both Screenpresso and Snagit, Screenshot Captor feels utilitarian and complex. But it's also very powerful, and perhaps more important, it's free/donationware. Screenshot Captor has all the same capture tools Screenpresso and Snagit feature, including scrolling capture. In fact, its scrolling capture feature even out-performed Snagit's in a PCWorld's review of a previous version... If you prefer a more traditional look to your utilities, or want to try a powerful free tool before shelling out money for a commercial alternative, you should try out Screenshot Captor. If you find it useful, consider donating to the developer.
