Hey guys, here's a nifty tool for converting an entire web page in to an image. Handy, simple, free.

Screengrab! is an extension that makes it easy to save a web-page as an image – it’s a screen capture tool for Firefox!

With it, you can save anything that you can see in a browser window – from a small selection, to a complete page.
