Might it help get more photos to have a forum designed to be a kind of *catch-all* for good, but unknown or uncertain of, photos?
For instance, I have a lot of photos of which I'm uncertain of cultivar names, etc. I know it's an iris; I know it's a TB, but other than that I know nothing. Someone who is more knowledgeable about irises could scan through the unknown iris images in that forum, find ones that they know what they are, and then propose them.
Just a thought.
