We have revamped the photo folders (formerly profile folders). Photo folders allow you to organize your photos exactly the way you want. Within these folders, you can arrange your photos freely. You can also design your folder description as a webpage with your own videos, slideshows, and photos. This opens up entirely new possibilities for showcasing your photos. You can now even assign public categories to your photo folders, making your photos discoverable through category navigation. Photos in photo folders are no longer visible only on your profile. Therefore, photo folders are now exclusively available to Premium members. Additionally, there is a new "Folders" section in your profile timeline, where your created folders are displayed with a preview image each.
HERE is a great example of how you can design your photo folders.
