Remove background layer from an image

How do I remove the background from an image? The image was scanned @ 300 dpi and has the file extension ".jpg"?

What sort of image on what sort of background?

Investigate layer masks -- they would help you here.

Basically text on a document once scanned created a white background.

The easiest way here would be to turn the layer into an ordinary (non-Background) layer by double clicking it.
Then use Layer Effects/Blending Options and move the white "This Layer" slider until the white disappears.
