"Can any picture be blown up to poster size?"

Not with satisfactory picture quality. You have to start with sufficient resolution.

Well they can. A low resolution picture will look awful grainy. A typical Internet sized picture would not look that good, but depending on its purpose it may be workable.

Yes, any picture can. But if it's low resolution it would be awfully grainy and "pixellated". If You have a school portrait, say 9x10, they can scan it in at a high res and blow it up to poster size without much loss of sharpness.......
