AI tools gravitate towards the visual language they saw most in training, and that language comes largely from stock photo archives. So when you write "business meeting" you get that image of smiling people shaking hands around a table that nobody believes.
The most effective way to avoid this is describing the concept rather than the topic. Instead of "remote work", write "a single desk above the clouds seen through the window of a mountain cabin". Let the image carry the article's idea, not its subject.
The second method is constraining the visual language. Describing a specific aesthetic — "editorial illustration", "isometric diagram", "risograph print", "technical blueprint" — pulls the model out of its default stock look.
The third is consistency: use the same aesthetic across every image on your blog. That builds a publication identity and tells the reader visually that the articles belong together.
