A simple Automator Action to import Screenshots in OSX into Photos:

• Select the Folder to which the Action is attached
• "Add to existing top-level album" - called "Screenshots"

I also have my Screenshots Folder on Dropbox, the Folder Actions are attached to that Folder.

dropbox_path = "/Volumes/3000/Dropbox/Library/Application Support/Cyberduck"
defaults write ~/Library/Preferences/ch.sudo.cyberduck.plist application.support.path dropbox_path
