Pictures on websites have always been either stolen from other sites a long time ago, then stock pictures from Unsplash or Pexels for a while, and now they're AI because that's just the easiest way to get images now. I don't think it's fair to developers to assume that the ones using AI generated images are also vibe-coding the software though. It's not like the ones writing hand-crafted artisanal code are also out with their cameras taking pictures for the website after all.

FWIW I don't disagree with you. I also assume people are vibe-coding things. I just don't think it's fair to assume that means the devs are taking that code and firing it straight up to a production server. They're probably fixing the problems and making it better. I know I do that in my code (most of the time.)
