How to remove Upload picture lable from registration page? how to remove Upload picture lable from avatar image field.
Something similar to this should work. Use form id alter hook to remove the label from image field.

function yourmodule_form_user_register_alter(&amp;$form, &amp;$form_state) {

 // Search for the field you want to alter 

 // unset the label using $form['search_image_field_name'] or remove the label using empty string for that form field.
}
