Working script uploading avatar in front end page

I read the threads and long agonized how to make the download.
Generally try, though, and the new version, but still …

<?php
global $user_ID;
if ($user_ID) {
	$user_info = get_userdata($user_ID);
	$id = $user_info->ID;
}

if(isset($_POST['user_avatar_edit_submit'])) {
	do_action('edit_user_profile_update', $id);
}
?>
<form id="your-profile" method="post" action="" enctype="multipart/form-data">
<?php
$myAv = new simple_local_avatars();
$myAv->edit_user_profile($user_info);
?>

<input type="submit" name="user_avatar_edit_submit" id="user_avatar_edit_submit" value="UpDaTe AvAtAr" />
</form>
