How to use the image file name in redactor editor

Question

while uploading an image in redactor editor, it itself rename the image file name with md5 encryption of current date and time. But i want to use the image file name.
You can see a live demo here: http://imperavi.com/redactor/
So, if a image file name is bird.jpg then i want to keep it as bird.jpg after upload it in editor, instead of something like this e1cbe0be9c301f7f73f3271a86508db3.jpg
How Images upload Works:
redactor.js file or by setting this option on load, for example:

<script type="text/javascript">
$(document).ready(
function()
{
    $('#redactor_content').redactor({
        imageUpload: '/modules/upload.php'
    });
}
);
</script>

Let's assume that upload.php file will handle images. Its code may look like this:

<?php

// files storage folder
$dir = '/home/web/sitecom/redactor/images/';

$_FILES['file']['type'] = strtolower($_FILES['file']['type']);

if ($_FILES['file']['type'] == 'image/png'
|| $_FILES['file']['type'] == 'image/jpg'
|| $_FILES['file']['type'] == 'image/gif'
|| $_FILES['file']['type'] == 'image/jpeg'
|| $_FILES['file']['type'] == 'image/pjpeg')
{
// setting file's mysterious name
$file = $dir.md5(date('YmdHis')).'.jpg';

// copying
move_uploaded_file($_FILES['file']['tmp_name'], $file);

// displaying file
$array = array(
    'filelink' => '/images/'.$file
);

echo stripslashes(json_encode($array));
}

?>

JSON example:

{ "filelink": "/images/img.jpg" }

so how to keep the $file to be the image name instead of the md5 data?

Answer 1

Change in upload.php

$file = $dir.md5(date('YmdHis')).'.jpg';

to

$file = $_FILES['file']['name'];

you get the file name in $file
