This is a good idea, and gets people working to update the data base.
I have come across several pictures where the plant was not already in the data base.
I don't mind if people here at ATP use my pictures, but I don't want people using them in the big "scrap books" that then charge money for people to use the pictures.
So I copyright them.
And now that we have done this------I will more likely note whether an image is in the data base--
either my own or others' !
