Picnik is an excellent web-based tool for editing images online. But this application has more features than what meets the eye. The Firebox browser extension for Picnik allows you to take a one click screenshot of any webpage. This feature might fail to impress at first glance. But ask yourself a question. How difficult is it to take a screenshot of a website that does not fit in your browser window. Instead of taking multiple images of different sections of the website use the Picnik Firefox plugin. After the install simply right click anywhere on the page and click Picnik. Firefox will load a new tab which takes you to Picnik with the image pre-loaded. Edit it if you wish and download the new image to your computer. This is one of the best ways to take screenshots of long webpages.
