The Photos library on the Kindle Fire gathers pictures from a variety of places, such as your Amazon Cloud Drive, Facebook, downloaded images from the Internet, saved attachments, and screenshots.
You can view, delete, and share photos on your Fire, but the device doesn’t offer any native photo-editing abilities. Search the Amazon Appstore for photo-editing apps if you need one.
When you first get your Kindle Fire and tap Photos on the Home screen, you’ll see a stock image that Amazon includes. You need to add photos to your Cloud or Device library.
The Kindle Fire supports three image formats: JPEG, PNG, and GIF.
