When I click on Public Uploads in my Photo Album it doesn't do anything. What's going on?
The Public Uploader option is meant to just be for your visitors, and the message is referring to the Upload Photos button in your Photo Album manager. The reason you're seeing this message when you click it is because you're logged into Bravenet.
If you log out of your Bravenet account first, and then go to the Photo Album page, you will be able to use the Public Uploader.
