title: Create an upload profile picture field in WooCommerce registration
body: <p>I'm using this code to add First and Last name to WooCommerce registration: <a href="https://stackoverflow.com/questions/40580190/how-to-add-custom-fields-to-woocommerce-registration-form/41290299#41290299">How to add custom fields to WooCommerce registration form</a></p>
  
  <p>I'm kinda lost on how to add a field for a profile picture upload. I thought I should use one of these functions (<a href="https://codex.wordpress.org/Function_Reference" rel="nofollow noreferrer">https://codex.wordpress.org/Function_Reference</a>) but it seems I'm looking in the wrong place. Is there a meta for user profile picture?</p>
