If you care about veracity then image generation works about as well as text. Frequently you can find details of the image that are just bizarrely wrong, such as hands or food or other basic things. It's the same basic problem: there's no intelligence behind what it's doing, it just regurgitates mostly realistic-seeming pixels that are pretty good at fooling the casual viewer.

Really, it's like those moths with eyespots on them: good at fooling the brain's heuristics but obviously not real.
