Oh, I have some code for that!!
It is based on the eBird batch upload of historical lists.
No photos are uploaded, it is just for adding historical observations of single birds if the species is not in my eBird “life list”. It is still command-line only, but someday I’ll turn it into an app.

The eBird location is inferred from the observation coordinates via the eBird API.
While I agree that this might not be useful scientifically, it makes the “life list” more complete.
