Great for sharing photo albums with the family and/or clients! Thanks, I missed this feature since iPhoto was discontinued.
I tried to it manually by exporting each album by hand, but the HEIC format of Apple Photos app on macOS ****** me off. :D This was solved perfectly.
I love the automatic resizing feature of photos, so my pageload of generated web galleries is great as well. My clients and my friends love it and I save plenty of time when sharing these albums on my website.
