How can you submit your own pictures on google?

Is there a way to reliably stop Google Nexus 7 2013 from syncing pictures to the web without removing syncing of calendars and email?

• I use my tablet for invoicing with an app that keeps my data under my control, though, SIGNATURES & receipts are saved as images in the gallery. To me this is a privacy issue, especially, since I am a Canadian and my Google data is not stored in my country but that of the untrustworthy USA. After installing an exif app I discover that the Nexus 7 2nd gen had been syncing my pictures to the web even though I had thought I had turned off the picture sync when really Google is only allowing me an "offline copy." If I explicitly turn off the sync features in the Gallery it turns it off for everything. Yes, I understand that Google claims that the uploaded pictures are for my eyes only. How many employees does Google have and what kind of access do they have? With a picture library of 300 gigs from the past 2 years of work I am very concerned where they end up. Why do I need to pay them for storage when I have a few multiple terabyte drives for backup myself. It appears to me that Google has removed "my freedom to choose" what gets uploaded to the web.

• Answer:

  As far as I know, photos are syncing thanks to settings in the Google+ app.  Check in there first to see if that helps you a bit.
