The images are from NASA/JPL.

The easiest way to use it is to orient yourself first on the small insert in the top right corner, then once you have the size and position you want, use your mouse to move around the larger picture.
On the very bottom is a linear size scale. Look how far out the Voyager and Pioneer spacecraft are!
