You can effectively group images in your media library, adding them into sets and albums. Sets work as folders for albums, albums are placeholders for images. To add a set:

- Go to Media library, click the “+” icon next to Library on the left

- In the pop-up window, you will see that Set is selected by default

- Enter the name of the set and its description (if needed)

To add an album:

- Go to Media library, click the “+” icon next to Library on the left

- Click “Album” in the pop-up window

- Enter the name of the album and its description

Now you can add images to albums, create sets with albums in them and organize you photos the way you want.
