Depending on the target age group, some classic choose your adventure books (as in the ones you could hold, and manually turn pages in) sometimes had pictures in them. In that sense, there’s nothing wrong with a picture, or two.
The only time I find it disruptive is when the image, or images–as the case can sometimes be on a single page–are very large, and don’t really add anything to the story aside from a bit of flair that games like these don’t really depend on to be well received. I don’t mind “cover art” pages. Those make sense from a stylistic standpoint. However, huge images in stat screens aren’t very appealing if they make it difficult to get at the info you’re trying to check.
So I guess my opinion is somewhat conditional. I have no issue with images, and even like them sometimes. But if they’re a bit cluttered, and far too large, that tends to mess with my enjoyment of the story.
