As Duane points out it makes a difference if the pictures were embedded in the post or added as attachments but it also makes a difference if you are logged into Router Forums or not.
I also use a password manager like the RoboForm password manager.
When I click on a link in a email and my browser has not been opened, the post will open the browser but it does not log me into the Router Forums because I am not logged into the password manager and the picture links act as Berry described.
If my browser is already open and I have logged into the password manager then it logs me into Router Forums and the picture links act as I described in my original post.
