How to save a web page as an image (jpg, png, etc) in IE9

I used to be able to use the IE7 Pro plug-in for IE8 and IE7 to save the entire web page as an image, but this plug-in is no longer supported by IE9. Now I have to find an alternative.

How can I do this in IE9? Are there any IE9-compatible plug-ins that can do this? I can't use print screen for this because that only captures the window itself and not content that must be scrolled to.
