Dropbox today announced a brand new app for handling photos called Carousel. In it, you'll be able to instantly back up pictures as you take them to the cloud, share photos with friends, view images by date and location, and leave comments on photos shared by friends.

Though the core Dropbox app has handled instant camera upload and back-up for some time, and even had dedicated views for images in the web client, spinning off the functionality into a separate app is a new twist, and vaguely reminiscent of Evernote's ever-growing plethora of in-house creations. In addition to Carousel, Dropbox today also announced the launch of Mailbox for Android and a beta of Mailbox for OS X.

The Carousel app will be going live on Android and iOS today. How many of you are already using Dropbox to back up your mobile photos? Do you have the need for a dedicated app, beyond what's already available?
