In this TEDx Talks, Joes Segal, Professor of cultural history at the University of Utrecht, gives a sort of an overview of what can be said on the politics of images.  Here, the politics of images represent simply the political impact of any kind of images created.

Segal poses a few questions that, according to him, are crucial to consider :
