    Great for downloading photos from your phone or camera through a computer and to mail pictures to relatives and friends. Mail pictures to family and friends or take it to a party of gathering to show your latest vacation photos on a smart device, laptop, tablet, or computer without cluttering up your phone or camera or computer with photos. Also if your computer crashes you still have your photos
