You will surely have identified that the images expressed a) Freedom b) Peace c) Solidarity d) Autonomy. But you might also have had some doubts about their relevance: Maybe you wondered whether the “peace” sign was appropriate in your context; and whether the image for autonomy might not rather suggest danger and risk for your audience and wondered if this image really expressed how they felt about their own desire for autonomy. And maybe many more questions. The more you are critical, the more demanding you will be on the right choice of images.
