I like that idea too. It would be especially useful if there was an easy way to pick photos that portray the characteristics being described (maybe even the option to draw an arrow or something). It sounds like it ultimately would have to be a separate thing or a mostly separate thing, but it might be able to be connected if keys could be automatically be constructed by the key characteristics the identifiers mention.
@tiwane Thanks! Hope it isn’t too close to the topic: “Investigate ways to capture comments and ID remarks that are useful for making identifications and including them on the taxon page and in identification tools” as written here: https://forum.inaturalist.org/t/inaturalist-2019-team-retreat-follow-up/373
I noticed the similarities after the fact.
