It's bloody frustrating, Google took over Panoramio and now demand that you have a Google+ account to access your own work. But to get that account you have to surrender your most private information to Google. I'm sure that if they were an Australian Company they would be taken to task by the government for breaching the privacy laws.
If you try to use their trouble shooting pages you get led into a series of interlinked loops that take you nowhere always ending with an Error message stating that you have provided an incorrect Username or Password, from whence you start on the same loops again and end up with the same message.
On one occasion I actually managed to find a Message page and asked that if they were no longer going to let me access my own work, that they remove it. They never answered nor removed my work.
