Dropbox is a free cloud storage service provided by Dropbox Inc. Dropbox offers 2GB of free storage space to store photos, videos, files and important documents. Dropbox allows user to create a special folder (Dropbox folder) on each of their computers for storing their files, photos & videos.
iPhone 5 has an added feature called "Camera Upload" in its Dropbox app. If you never enabled the "camera upload" on another device, then it will automatically create a "Camera Uploads" folder in your Dropbox account where the uploaded photos will be stored.
