Thanks for all your help and understanding! I would not have changed to another account  if someone had not changed one number on my mobile phone so I could not get back into my account. My password had suddenly changed and I was locked out!

Yahoo Mail doesn't have a mail export feature. It cannot be moved out of your account to another location. They can only be forwarded one by one.

The pictures, you download them to your device, then upload back to the new account. For mail, you forward all those emails to the new account. There is no way to directly transfer between accounts.
