Scrolling

BlitzPlus Forums/BlitzPlus Beginners Area/Scrolling

Hello, I haven't been around due to time constraints- but on any note, here I am with yet ANOTHER anoying question. I have always been confused with scrolling. Is it just one big image were you add x and y to make it appear to move? Or is it a combination of images like a puzzle? What ever it is, it would also help me very much if an example were provided.
Help profoundly appreciated,
Siopses
