Here is a neat little program I found. Here is the info on what it is and what it does (cut and pasted from the site):

IECapt is a small command-line utility to capture Internet Explorer’s rendering of a web page into a BMP, JPEG or PNG image file.

You can use IECapt for example for batch processing, to make screenshots of the entire web page rather than the currently visible area or in a CGI script hosted on a Windows web server to provide access to IE’s rendering engine from non-Windows computers.

I can’t think of any real reason to use this little program. But it’s handy for taking a whole screenshot of a webpage. It does seem to default at a screen width of 800. I say that only because most sites are best viewed at 1024×768.
