Squarespace 6 can create new pages based on folders you add to your Dropbox account.

Once you hook up your Dropbox account in Squarespace’s social management panel, you’ll be able to click the listing to get the full instructions that you see below.

In a nutshell: a new /Apps/Squarespace/ folder gets added to your Dropbox, and any folders you place in it can get turned into Squarespace collections (pages). Create your folders, add your images, and wait for them to finish uploading. Then, visit your Squarespace social panel and hit the Publish to Squarespace button to make the magic happen.

For now, this integration only supports images, or, really, photo galleries, but it sounds like they’re aiming to expand it soon.
