Here are the steps to Save Photos from Shared Albums to Photos Library: Open 'Photos' app on your Mac. Click 'Shared' button located at the toolbar. Double-click the shared album. Select the photos which you want to save. Control-click a selected photo and choose 'Import' option. You will see your imported photos in the 'Last Import' album. Click 'Sync' to copy the content to the Pictures library on your computer. If you have a Windows Phone, you can use the Windows Phone app to sync your pictures with your PC. Once you've transferred the appropriate content to your computer, you can then connect to your Kindle Fire and copy the photos over USB.
You can store your library on an external storage device, such as a USB or Thunderbolt drive formatted as APFS or Mac OS Extended (Journaled). However, you can't move your library to a disk that's used for Time Machine backups.
To prevent data loss, Apple doesn't recommend storing photo libraries on external storage devices like SD cards and USB flash drives, or drives that are shared on a network.
Make sure that the drive is turned on and available to your Mac before opening Photos. If Photos can't find your drive, it stops using the Photos Library stored there.
After you open your library from its new location and make sure that it works as expected, you can delete the library from its original location.
In a Finder window, go back to your Pictures folder (or whichever folder you copied your library from) and move Photos Library to the trash. Then choose Finder > Empty Trash to delete the library and reclaim disk space.
If you have multiple libraries, here's how to open a different one:
Photos uses this library until you open a different one.
If you have a permissions issue with your library, you might be able to resolve the issue by using the Photos library repair tool.
* If the volume isn't formatted as APFS or Mac OS Extended (Journaled), or has been used for Time Machine backups but hasn't been erased, this checkbox will either not be present, or it won't be selectable after unlocking. Erase the drive for this option to be available.
You can easily import photos and photo albums from iPhoto to Amazon Cloud Drive. You need to download and install 'Amazon Cloud Drive Desktop' app on your Mac. To import photos from iPhoto, open 'Amazon Cloud Drive' app on your Mac. Click the Cloud Drive menu bar and select 'Import from iPhoto' option. Now you can select multiple iPhoto albums sorted by events. When you select events from iPhoto, Amazon Cloud Drive Desktop app seamlessly uploads photos to your account. You can also upload photos to Amazon Cloud Drive simply by dragging them to your menu bar. You can access those photos instantly on Kindle Fire or from any web browser.
