We introduced photos on Facebook more than a decade ago, and they quickly became one of the main ways that people share their experiences with their friends and the world. Hundreds of millions of photos are shared on Facebook each day, from fun snapshots to photos of major life milestones, and everything in between. Today, we’re improving photos on Facebook so that people can share more immersive views of their world.
Facebook profile picture dimensions are 160x160px but you should upload at least as 180x180px and facebook will scale it down
For the first time, you can now easily share 360 photos on Facebook. Simply take a panorama with your phone or capture a 360-degree photo using a 360 photo app or 360 camera, and then post it on Facebook as you would a normal photo. From there, we’ll convert it to an immersive 360 photo that people can explore, similar to how people experience 360 videos on Facebook

They’re now more important for design and identity on the user interface, like your profile picture or cover photo. And it’s a great way to share photos in galleries and on the timeline. Facebook photos are now a huge part of the site’s appeal even as dedicated image apps like Instagram have become hugely popular as well.
