Scrolling Background without Tiles

Hi all. I read an interesting post about creating big backgrounds that scroll with the player without using tiles.

Some interesting points were raised and I think I might give it a shot. I'm totally new to this whole graphics thing though so I have a question:

If i create a huge background, bigger than my screen like the guy in the post suggested, how would I go about displaying only part of it and scrolling through the rest?
