"images need words, and both become inseparable in media work. They reinforce each other and offer a basis for making meanings that rests on the power of the visual experience and the authority of the word, connecting the present and the past and producing a context for interpreting the world".

Hanno Hardt and Bonnie Brennen, Picturing the past. Media, history and photography, University of Illinois press, urbana and Chicago, 1999, p.5.
