How can make picture upload required on HMS testimonial module?
Here the code bribe about that field :
if (isset($_FILES['hms_testimonials_image']) && ($_FILES['hms_testimonials_image']['size'] > 0) && $settings['form_show_upload'] == 1) {
$get_file_type = wp_check_filetype( basename($_FILES['hms_testimonials_image']['name'] ) );
$uploaded_type = $get_file_type['type'];
if (!in_array($uploaded_type, $allowed))
$errors[] = apply_filters('hms_testimonials_sc_error_image', __('You have uploaded an invalid file type.', 'hms-testimonials') );
}
