Login Screen Modification

Hello, I am currently working on modifying my login screen for personal design. I have a question. In the beginning at the login screen where you login it has the square where you login picture is and the password box. Is there any way to move the picture box and password box to a different location on the screen? What I'm asking is if it can be done and if so how to do it. I would prefer to align these items say to the right or maybe to the upper right part of my screen. I appreciate all help in this and to all that do assist thank you in advance.

Thank you very much Jerry I deeply appreciate the information. I will definitely be creating a restore point before trying anything.

Thanks for the info Julian I will work on this and see what I can come up with. Also thank you Jerry for the information and link to the program.
