Automatically create a Wordpress gallery on a specific post from a Dropbox account

I'm working on a Wordpress project where a client would like to automatically create a new image gallery in a post by adding a new folder of images to a Dropbox account. See attached image. Dropbox element could be eliminated if too complex. The posts will be a custom post-type and the Brand of store will be a category within custom taxonomies.The images will be pre-sized before upload so no need for cropping functionality. Gallery of thumbs clicking through to a lightbox. PHP scripts will execute every 5 minutes to ensure content is continuously up-to-date.

Can I do this in conjunction with you plugin as tool to manage the images? Thoughts, advice, warnings?

Thanks
Mike
