You do not have to use generative AI "art" in your blog.  

Jenn Schiffer shares a useful list of websites where you can get beautiful, free images licensed for use in your creative projects.

I enjoy a few blogs and newsletters that obviously use gen AI to make header images. Those images do the writing zero favors. As I writer, I understand the impulse to outsource image generation to an AI tool where you can describe what you want with words. But just because you can, does not mean you should. Imagery that’s obviously generated by AI has a who cares smell about it, and I don’t use it here.
