SightSnap lets you take a screen shot of any website. You can also use SightSnap as a web service to grab a screenshot whenever you need. Look for integrated immage effects, custom croping and more within the next few weeks.

For each SightSnap request you make, you must provide three parameters. The URL of the website you want to capture, the width (x) in pixels, and the height (y) in pixels. Take a look at the link below for refference:
