I noticed quite a few of those recently too, some seemed to be from new members. I think it would help if on the main landscape photo page (
https://garden.org/plants/mult...) there was a hard to miss brief explanation of what photos are appropriate for it, right above the upload button. Explaining that if there is only one plant seen or tagged in the photo then it would be more appropriate to add it to the plants database. Providing a link to the plants database right on that page as well would help direct people to it. Is there a comprehensive article that explains all the various aspects of sharing photos here (plants database, landscape photos, inserting in posts and swap lists, and linking pictures posted to the database)? If so providing a link to it at all places people might upload photos from, might help too.
