Imago or imagination is mental image based on memory. Similarly as JPG files, images are compressed for easier retrieval. We often forget that images are stored as complex memories, involving emotions and space/events. Imagination may be regarded as retrieval of these imago-emotions and attributed to generate new (imaginary) images.
We should pay attention if term we use relates to visual sensation we try to describe. That’s why it is important to say that technology-generated “images” and not images at all. They are mechanically reproduced pictures of photographs without imagination.
