title: I am planning to create the api for signing up the user
body: <p>Whenever the user registers with signup link, along with the data I want to send the default user image to the api. But I want to do this without clicking choose file button, I want the file to be sent in background</p>
  
  <p>Note: Default image file is present in project directory</p>
  
  <p>this.authHttpService.signup({...this.signupForm.value, file????});</p>
  
  <p>how to send the actual image file present in the project directory?</p>
