If you have an album that has too many photos, you can split it into two separate albums. Select the photo in the album where you want to make the split. The photo you select will be the first photo of the new album. Click the arrow button on the selected photo, select Split Album Beginning Here from the menu, and give the new album a name. The photos from the selected photo to the end of the album are moved to the new album folder.
Note: Before splitting an album, you can change the order of photos by dragging individual photos to different positions in the album.
