Your thinking is too complicated. After submitting your resume, whether you put the picture in the text as an attachment or directly in the text, you should call the employer to let him know that you submitted your resume. And one of the advantages of calling is that if the other person asks about you, you can introduce yourself on the phone, so that the other person may be more impressed with you. And there is another advantage of this method that you are more confident, because most people just send emails, just wait there, and you take the initiative.
