Does it let you take a screenshot of the whole height of the page? I see that you can specify the height of the viewport, but what if I want a whole long screenshot of as much height is rendered?
Of course there are limits to this as some websites have "endless" scrolling (like pintrest)
And using 400x400 viewport: http://www.url2picture.com/Picture/Png/?apikey=6101EE5C99B14...
