I had changed my email address and photo contact address a few months ago.
First I logged into my members (photo) section using email address & password.
(logging into the forum section, you have to enter user's name and the associated password if it's different than the photo section login.)
(Two different ways to log in, but access to all areas...)
I've attached a image of the member's section page.
Number 1. go to account info
Number 2. change your email address and hit update.
Number 3. Batch change all the photos with your new address.
Worked for me, but it may take a few hours to take affect :-)
YOU should log out, after email change (#2) then log in with new credentials - BEFORE doing (#3) - JUST IN CASE of Gremlins !!!
