QuickShareIt vs. Dropbox droplet
After finding this page with dropbox addons via @dotdean
http://wiki.getdropbox.com/DropboxAddons
It works fine, but i have to say that i like QuickShareIt better because of the short-URL you get when uploading pics. Compare: You can find the tools here, they are free:

ps: i added a few slashes to the dropbox link suffix, so that the link is shown not the pic...
