The Google+ Photos app we saw Google release last June for the Pixel is now available for all Chromebooks
The Google+ Photos app was always able to be installed and "hacked" to work for Chromebooks and computers that weren't the Pixel, but now you can officially load it up and run it on all Chromebooks. The application allows for easy sharing photos from your Chromebook, and is a great front-end for viewing and sorting out your Google+ photo collection. It even starts up when you insert an SD card with pictures into your Chromebook.
Installation is easy, you just click and install from the Chrome Web Store. If you have a large collection of photos on Google+. or plan to build one, and use a Chromebook you will want to give this one a look.
