Okay, I was able to upload photos via the My Account -> Manage Photos -> Upload Photos route. What didn't work, was for a river with no photos, such as this one:
Etowah 2
The "upload photos" link does not work properly. It pops up a form, but, at least when I tried it on the 7th, you fill out the form, click upload, and nothing happens. Only thing I see different, is that it doesn't ask for the watershed info (first screen on "Manage Photos" route), but I'd assume it would derive that info from the fact that I clicked upload photos on that particular watershed page...
Anyway, since I can upload photos (
Etowah 4), and I want to keep my rivers open, I'm signing up as a paying member!
