(Don't know of one to use Mozilla's renderer, though.)

Awesome : http://wkhtmltopdf.org/

wkhtmltopdf and wkhtmltoimage are open source (LGPLv3) command line tools to render HTML into PDF and various image formats using the QT Webkit rendering engine.

Somebody wrote a blog post about this a few years back. There are examples in several languages, using both WebKit and Mozilla. There's also an example in Ruby.

It boils down to this: decide how wide you want your window to be; put a browser component in the window; wait until the page loads; capture the pixel buffer contents.

Using Firefox, you will need the screengrab addon.

I'm not sure if this is quite what you're looking for but I've had a lot of success using an HTML to Postscript converter html2ps to create postscript copies of web pages, which I then convert to .gif or .pngs

This doesn't produce exact screenshot quality that you'd get from a web browser and doesn't handle complicated things like flash or css all that well, but the advantage is that you can run it on the web server.

(I use it to create thumbnails of user created content, for navigation)

Not sure if this is what you want but this is what I do sometimes in a pinch when certain websites are not saving right.

I just print them to PDF and I get a PDF file of the 'print output'. There's an Microsoft XPS Document writer under my list of printers as well, but I don't use it.

Hope this helps! =)

You could use imagemagick and write a script that fires everytime you load a webpage.
