Dropr

The Dropbox WordPress Plugin – Dropr lets you access files from your Dropbox account and help you to add them straight to your WordPress website. Securely and safely.

How Dropr Works
Dropr essentially turns your Dropbox account into a secondary WordPress Media Library. You can access your Dropbox files from the WordPress text editor screen, then drop files into your content as you please without ever having to upload them to WordPress.
