I'm using Dropbox as my primary auto-upload tool from iOS, and I'd like to streamline the process of getting photos to Flickr. Rather than using the Flickr iOS app's built in auto-upload, I'd like to only upload the photos once (via Dropbox) and then have something monitor the Camera Uploads folder on the Mac for new files.
Is there a tool that monitors a folder on a Mac and uploads any newly added photos to Flickr with privacy set to private?
