Just an update: It was very easy, guess I was intimidated about the picture. Took quite a few pictures but the first one I submitted worked. Helpful hints: crop the picture before you download from phone to pc, makes the file smaller and faster to download. Use Bluetooth and not email. Once in pc enhance the brightness if the background is not "white" enough. I got my renewed passport back in about 2 weeks but my wife's took a few weeks longer for some reason, we applied the same time.
Hope this helps.
