I can’t find it now (edit: I found it!), but I remember seeing an observation of a eucalypt a while ago, and the photos were awesome because the observer had taken the time to basically photoshop labels that pointed to diagnostic features all over them.
I think it’d be really cool to be able to do that in iNaturalist itself—for example, to label diagnostic features or to point out something odd or even just to ask for more information or help about a feature (e.g. is this a sepal or a petal?). It’d be good if an identifier could also annotate someone else’s photo in the same way.
I guess I envisage a system a bit like Facebook’s face tagging feature (minus the auto-recognition, although that could be cool too) where labels or clickable hotspots pop up when you hover over the image.
