Foren / Cotonti / Support / Extrafield file, how to use it?

Hi, i have one question. How to use extrafield file? When i add an extrafield i.e. img and add in page.edit.tpl tag {PAGEEDIT_FORM_IMG} it only display an "Array" text.

v 0.9.3, this same on snapshot made from git 4 days ago.

base html generated by Cotonti. i've just put name and descr.and type of field

function  cot_build_extrafields from  /system/extrafields.php returns an array for "file"

case 'file':
			$R["input_text_{$rc_name}"] = (!empty($R["input_text_{$rc_name}"])) ? $R["input_text_{$rc_name}"] : $extrafield['field_html'];

			$result['FILE'] = cot_inputbox('file', $name, '');
			$result['DELETE'] = cot_checkbox(false, 'rdel_' . $name, $L['Delete']);
			$result['LINK'] = htmlspecialchars($data);
			break;

But how to display each 'record' from this array?
