Superfluous Images

One development that I don't understand amongst certain law-professor blogs is the use of superfluous images to accompany blog posts. Money Law is one of the worst offenders; among many examples, this brief post merely links to another blog post about law schools, but is accompanied by a picture of a man in a checkered shirt, and this post about law school rankings is accompanied by a large picture of a tennis visor (all for no apparent reason). Why such an incessant drive to add irrelevant images, or even marginally relevant ones? It clutters up the page, and makes the page take longer to load. Apparently some people have the notion that a webpage is more eye-catching if it has a bunch of colorful images rather than unadorned text, but I would imagine that law professor blogs draw a readership that may find such images more distracting than anything else. At least that's the case for me.
