How to send email images to node js server with Axios without a form?

How do I send an image to my node js server with axios in react without a form? I'm using nodemailer on server side to send an email with text and an image attachment. The code below is what I have and it does not work as I'm not actually sending the file itself. The code works fine for sending text.

import img from "./image.jpg";

const handleRequest = async () => {
  const body = {
    img,
  };
  await axios
    .post("http://localhost:3030/mail", body)
    .then((res) => {
      console.log("Email Sent Successfully");
  })
  .catch((err) => {
    console.log(err);
  });
};
