Reverse sync – Is it possible?

I’d love a feature where this service retrieves the content of a specified Dropbox folder from your account and syncs it to the web server.

For example I have a Dropbox image directory that that has its content generated on and by a local machine. I need to keep that synced with an image folder on my WordPress installation.
