I'd disagree with your take on the need for generic pictures. They may not be needed for information, but for structure and context. Unless you're writing for machines only, You should care about how your information is processed.
So ESPESCIALLY in an info-overload-world, presentation matters, as it helps with processing.
Take a fast food menu. 3 or 4 basic dishes with 60+ variations. Either spread out on a huge wall behind or above the counter, or crammed on a single two-sided laminated sheet. Generic pictures can help to guide you to the beverage or pizza section fast. So that's structure and visual cues, and not useless eye candy.
The other end is the menu in a $$$ restaurant. The menu is structured by seperate pages for each group, and probably no more than 7 dishes per page or block. And again lots of work went into the presentation, too, though the "eye candy" here isn't generic images, but layout, fonts and spacing. You COULD press the same menu on a single laminated sheet without technically loosing information, but you make the information harder to access.
