A holo-image was a holographic reproduction of a three-dimensional scene or object, similarly to a photograph, that could be created with a holographic imager. Talaxian technology included the ability to generate holo-images, however, if not properly maintained, they could fade over time. Neelix lost his entire family to the metreon cascade.
