Yes, iNat isn’t a good fit for pictures of museum specimens (unless the observer is the original collector). They can be tolerated in small quantities but would need to be downvoted for “Wild” in the DQA (as the organisms didn’t intend to be at the museum) and uploaded at the museum at the present day (when the observer interacted with them). Observers shouldn’t add photos for museum specimens with the original place/time of location unless they made the collection themselves.
There are a fair amount of previous threads on the forum that address this that have more details about this issue.
