I like to send a picture which will appear in the center of the recipient display.

You have no control over a recipient's email client behavior nor the remote ability to detach that picture from their received email and display it in the center of their screen.
You can attach a picture and then using your Mail compose window's paragraph tools, center-align your attached picture in the email before sending it.
