The Pressbox plugin adds a new tab to the Media Upload screen that allows you to insert images and files from Dropbox into your posts.
Additionally, the plugin provides a new shortcode that lets you add links or display images anywhere you want on your blog.
This plugin is under heavy development so please feel free to send me feedback, bug reports, and feature requests!

This plugin bears a great debt to the work of Joe Doleson’s Wp To Twitter plugin for his excellent example of OAuth integration with WordPress.

Pressbox

Integrates DropBox with your blog allowing you to post images and files directly from your DropBox. Requires PHP 5.2 and cURL.

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.

Dropbox Photo Sideloader

Especially now that Dropbox has added a File Requests feature, this Sideloader plugin is a lifesaver. Version 0.6 of the plugin is working just fine for me. No problem loading images with spaces in the filename - spaces were converted to hyphens once they arrived in WordPress Media Library.
Thank you :)



Got it to work - very nice
