In Google+, it's exceptionally easy to import photos. If you've got the mobile app installed and allow it, your phone or tablet will upload every single photo you take on your device into a private folder. This tutorial shows you how to take those photos and edit them from your laptop or desktop computer.
To get started, click on the photos button on the top of your Google+ screen, and then click on Photos from your phone. You could use photos from other sources, of course, but being able to edit photos from your phone before you make them public is one of the most useful features of Google+. In my case, my son loves to take pictures of himself on my tablet, so I'll start with one of his self portraits.
When you hover over a photo, you should see a little magnifying glass. Click on one of the magnifying glasses to zoom in. That will take us to the next step.
