I hated Google+ when it was launched as a social network as it was forcing us to sign up for a Google+ account to use other Google services (like YouTube, Gmail, Picasa Web, etc.). But then I learned to love Google+ because of Google+ Photos.
Google+ Photos was a revamped version of Picasa Web Albums. I was able to explore all my Picasa Web Albums (oh yeah, it was my favorite photo storage service) in Google+ Photos and then there was a handful of powerful features like Unlimited Storage (up to 2048 x 2048 px), Auto-Backup (to backup every single photo on your phone to Google+), Auto-Enhance (a fantastic online photo editing tool), Photo Sharing, etc.
As you probably know, Google dropped the “+” from Google+ Photos and now it’s simply known as Google Photos (in other words it’s now a standalone product).
That’s not all! Google Photos offers free unlimited storage for photos up to 16 MP or around 4,000 x 4,000 px (up from 4 MP or 2,000 x 2,000 px). Voilà! Google Photos is a standalone product and it’s got over 200 million monthly active users. In fact, it’s one of the best Google products ever.
It’s great because Google+ Photos was such a great application for photo storage and organization but was actually hidden inside an ugly social network.
