I know you mean well and I understand what you're trying to do. Yet I must maintain the illusion of some consistency here :) We do need a better solution for this, the ability to upload anything (docs, photos) as part of a species record.
For the time being, I'm removing the ID yet feel encouraged to still include it within the context by means of an image link, or tags.
Hope you understand. Posted 6 years ago
The reason I disagree is this: This here description _IS_ the species. Within the concept of species, a species is only valid when described and named properly in the context of a publicly available publication. Today, it is imperative that a description of a new species is accompanied by the deposition of one or more type specimen in a collection, but historically that has not always been the case. And where it has been the case these type specimen have often been lost after hundreds of years of storage; eaten by other bugs, spontaneously disintegrated, destroyed by war, or simply disposed of by someone ignorant enough.
So more often than not, all we have left is the original description (or an excepted redescription by a later author). THAT is what defines the species. Put differently: Only the type specimen that came with the description (if still in existance) and the description itself are what define the species. _All_ other specimen (or images thereof) that refer to this species name are merely a matter of OPINION that these would concur completely with the described species and often this opinion is changed over time.
Looking at it from that perspective, you may understand why I think it is valid to classify an original description under the species name, but of course you're entitled to your own point of view ;o)

I still would prefer a future feature where we can separate between "normal" images and supplemental material, but that one's on me. Posted 6 years ago
