Views.fm is a web app that uses the Dropbox API to enable users to share and receive online photo galleries from others.

Views.fm lets you quickly and elegantly present files on the web. Presently, it supports Dropbox. Files are automatically organized in an easy-to-scan thumbnail view, and you can create either public or secure, private shares. You connect your Dropbox account to Views.fm and can then share Dropbox files and folders through the site.
