Images give rise to diverse perceptions, and this abolishes any inclination for "reading from the image". On the other hand, in places images suggest the elements of an understandable vocabulary following established civilisations - and today with global effects. But are all images visible? Hidden images lie dormant in the collections. Often they are wrongly identified, confusing primary and secondary images. Moreover a lack of university courses allowing for the development of interdisciplinary research in this domain leaves out whole sections of still or moving sources. Progress in the history of the visual from a worldwide perspective must allow the establishment of benchmarks for the widespread storage of icons. They will serve creators equally by offering a narrative potential for a variety of purposes.
