I have a Samsung galaxy s3 and a nexus 10. I'm trying to sync my pictures from my s3 to my Google plus account so that they will automatically get uploaded and I can access them from my nexus. Once I set it up all the pics I click from my phone get uploaded automatically. But any pics I receive from whatsapp or which I download don't get uploaded to Google plus. How can I make this happen? I get many pictures on whatsapp which I would like to get backed up. Pls help, thanks!
