Unfortunately, you can't sync the media on your smartphone with your Kindle Fire without using a third-party application or service. The easiest way to share photos between devices is to use your computer. If you have the iPhone or an Android device, you can import your photos to your Pictures library using the Photos app in Windows 8. 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.
