How to upload photos from the frontend?

Question

OctoberCMS

title = "testupload"
url = "/testupload"
is_hidden = 0
child_of = "mey_no_parent"
hide_crumb = 0
remove_crumb_trail = 0
crumb_disabled = 0
[Ajax]
use_authors = 1
restrict_owner = 1
backUser = 1
allowpublish = 1
postPage = "blog/post"
[Responsiv\Uploader\Components\ImageUploader imageUploader]
placeholderText = "Click or drag images to upload"
maxSize = 5
fileTypes = ".gif,.jpg,.jpeg,.png"
imageWidth = 100
imageHeight = 100
imageMode = "crop"
= =
<?php
function onInit()
{
$this->fileUploader->bindModel('photos', ????????? );
}
?>
==
{% component 'Ajax' %}
{% component 'imageUploader' %}
I can't figure out what should be instead of questions? Are there any examples?
