I think you should learn from the reaction of most people in this thread and avoid it (if your audience is mostly technical people) for the following reason.

A. If it's unrelated, it doesn't add anything to the post except aesthetics. B. On the aesthetics dimension: I don't think people are very impressed by the AI aesthetic, and tend to be annoyed by it. C. It seems that most people now assume that AI-generated image == AI-generated text.

I personally do not care about AI images or not, but it seems that a portion of people do.
