I was using Google picasa for picture sharing and that has now been retired for the supposedly better Google pictures.
It does not let you share the same way and is not so user friendly. If you are logged into your google account it shows the picture you post hence did not know their was an issue with the post until I was on another device.
Thanks again Jenny for highlighting the need for volunteers.
