Concrete pictures should illustrate clearly what a thing looks like, without irrelevant details and strange angles. However, abstract pictures can also be used to express atmosphere or feelings, for instance. Other criteria apply in that case. It is important for form and layout to be well thought through. It is easier for the reader to absorb information if text and pictures are presented as clearly and with as much space as possible.
