This article describes how to find your Photobucket email alias (also: 'email drop box') that was created by Photobucket when you signed up for the service.
The Photobucket email alias can be added to the "receiver email"-field of the "email it" action. By this you can forward photos from Dropbox to YouTube.
Here is how it works:
- Sign in to Photobucket.
- Click on your user name and select "Account settings" from the list.
- In "Account settings", select the tab "Mobile" and copy the mobile upload address. This is your Photobucket email alias.
