Apple was very thoughtful when putting screenshotting abilities in OS X. They included the “Grab” application, which allows you to capture the screen, a selection, or just a window, and then decide what to do with it. But what happens when the window isn’t big enough to capture everything you want, say a screenshot of a full web page. That’s the question I was asking before I started a search and finally came across Paparazzi for OS X. Paparazzi allows you to enter the web address, and dimensions you want for your screenshot. Then all you have to do is hit capture, and you have a full web page screenshot resized to the dimensions you specified.
