You can mark important photos as “Favorite” and see all those photos in one album.
It works just like email’s starred messages. You can put a star on each photo, then you will be able to see them in “Favorite” album. If you’re carrying a bunch of photos in MyPhoto, this will be a good solution for you to keep important photos in one place. ;)
1. Settings
You can turn on Favorite Album if you want to use it at Settings>Albums>Favorite.
(iPhone)
2. Mark photos as favorite
In each photo, you can see a star on top right side of photo. Tapping it, you can mark the photo as favorite. Once marked, the photo will be shown in Favorite album.
(iPhone) 
3. Check favorite photos in Favorite Album
On home of MyPhoto, you can see Favorite album if you have already activated it. In the album, you can see all favorite photos at once.
(iPhone) 
This is only showing the photos in one place, the original photos are located in each album where they used to be. Thus, in Favorite album you can only share photos, not edit or move.
Effect+ is more powerful photo editor in MyPhoto. You can automatically enhance, apply filters, put stickers, reduce red eyes, etc.
