in theory if XYZ Medical and ABC medical get into a war of replacing the image with better and better ones, while making their logos smaller or smaller, the articles win by ending up with the best photos of all. so it's a question of whether the result is objectively better. the shilling concerns you raise about article text are more than real. they're a battleground of socket puppet manipulation. in theory that's why things have to be sourced, original research isn't allowed, neutrality has to be kept, etc. but in practice it's a really bad. so I'm much more concerned about article text than I am about images and you raise a really valid concern.
