// PHP:

add_filter( 'gform_file_upload_markup', 'change_upload_markup', 10, 4 );
function change_upload_markup( $file_upload_markup, $file_info, $form_id, $field_id ) {
	return '<strong>' . esc_html( $file_info['uploaded_filename'] ) . "</strong > <img class='gform_delete' src='" . GFCommon::get_base_url() . "/images/delete.png' onclick='gformDeleteUploadedFile({$form_id}, {$id}, this);' />";
}


// JS:

gform.addFilter('gform_file_upload_markup', function (html, file, up, strings, imagesUrl) {
  var formId = up.settings.multipart_params.form_id,
  fieldId = up.settings.multipart_params.field_id;
  html = '<strong>' + file.name + "</strong> <img class='gform_delete' "
  + "src='" + imagesUrl + "/delete.png' "
  + "onclick='gformDeleteUploadedFile(" + formId + "," + fieldId + ", this);' "
  + "alt='" + strings.delete_file + "' title='" + strings.delete_file + "' />";

  return html;
