We analyze a scheme consisting of an optical parametric amplifier and two imaging lenses. From an off-axis input image such a system creates two quantum entangled output images, signal and idler, symmetrical with respect to the optical axis of the scheme. In the limit of large amplification the idler image is a quantum twin of the signal one in the sense that they display identical intensity fluctuations in space-time.
