Dropbox Photo Sideloader

Adds a new tab to the Add media screen, allowing you to pull images from Dropbox into WordPress. "Sideloading" is a term given to differeniate from "uploading" or "downloading". When you sideload an image, you're copying it directly from Dropbox to WordPress. So if you keep your images in Dropbox, this plugin allows you to easily copy those images into WordPress. After sideloading an image into WordPress, you'll find it in the Media Library and available for use in Galleries, or as images in the Post, or just whatever you like. It's just as if you uploaded them manually. Note that sideloading many images at once may take more time than your webserver will allow. If this happens, just sideload them in smaller groups. Credits:

• This plugin uses the Dropbox PHP code (albeit modified slightly) from https://github.com/Dropbox-PHP/dropbox-php.
• This plugin uses the jsTree Javascript library from http://www.jstree.com/.
• The three image icons come from the Lullacon Pack 1: http://www.lullabot.com/articles/free-gpl-icons-lullacons-pack-1

Setup:

• Install the plugin.
• Create a new post (or edit an old one), and click the Upload Media icon.
• In the uploader popup, click the new "Dropbox Images" tab on the right.
• If you're logged in as an administrator, you'll find configuration instructions. These only need to be followed one time.

Those configuration instructions are reproduced here, for clarity.

• Visit https://www.dropbox.com/developers/apps and Click "Create an App".
• Give it a name and description.
• Select "Full Dropbox" so that it can access all your files.
• After the app has been created, copy the App Key and App Secret into the plugin config screen.
• Note: You can leave the App in "Development" status unless more people than just you need to access their Dropboxes using the plugin.

0.6

• WordPress Core now handles spaces in sideloaded images, allowing me to fix this issue in the plugin. Ref: https://core.trac.wordpress.org/ticket/16330
• TODO: Support new media library properly with JS, instead of using the backwards-compatibility functionality.

0.5

• Add preview panel on the right hand side of the screen for WordPress 3.5 users (who now have a bit of extra width to play with)
• Fixed ordering of directories and items
• Added uninstall script to remove the dbsideload settings on uninstall

0.4

• Add new jsTree based file browsing and image icons.

0.3

• Add error handling and error checking to the setup process (test for an invalid key/secret before saving them).
• Change to use mobile version of the auth screen (looks better, IMO)
