This project led me to propose the Taft Test:
Does your page design improve when you replace every image with William Howard Taft?
If so, then, maybe all those images aren’t adding a lot to your article. At the very least, leave Taft there! You just admitted it looks better.
Two reasons: The people in the pic look more or less like our real ourselves. The synthesized photo shows the process of discussing highly conceptual approaches, which was our everyday for 10 years or so.
