The popular photo application is premiering its new function, or rather a function that we have already seen in another application. These are "Collections", if in the pure style of Pinterest.
With the private collections of instagram photographs you can save all your favorite photos from different accounts and save yourself being looking for them whenever you want to see them again. The collections work anonymously, that is, no one will know that you keep your photo in your collection.
The folders you create will appear in the tab of the "Saved" section. To add a photo to your collection is as simple as holding down and choosing which folder you want to save it to.
