Do I title, caption or have some explanatory statement alongside images within the text?
Or do I leave the reader the space to critically reflect on the content?
Maybe I come with the approach - reflected in the literature - that if the images are strong enough they need not be accompanied by words.
What I would instead do is perhaps have a hyperlink to the list of images? Perhaps with an identifying number? Or perhaps I reproduce the image smallsize, alongside a caption, organised by section within an appendix or similar.
This way, the reader has the space to draw her own critical conclusions on the image alongside the text, but can seek clarification and 'bibliographical detail' as desired as a later time, without interrupting the flow of the audience experience.
