yes, I am testing again.
What I have found is that when you entered the Email Address * - theremotedr@gmail.com
no image was displayed, but when you entered the Email Address * - i.parsons68@btinternet.com
the image was displayed.
So that, obviously, is where the "Gmail" problem resides, as the same thing happened with my tests.
If you are intent on using "Gmail" you will have find out from Google a method to stop them blocking
your potential customers domains or go back to just having it's address displayed.
I await your comments with interest.
I will now return the php to your email address so that you can test my assertions yourself.
