RewriteRule lowercase transform for file names only

I'm trying to redirect Capital Case file names only to a lowercase file on the server, retaining intact directories case.

I don't have access to httpd.conf.

I have found this that do the trick with php and RewriteRule but in my case I'm unable to capture the directories between $_SERVER['HTTP_HOST']/base/ and filename, so I lost them in the redirection causing an apache fail.

The rules are:

RewriteEngine on
RewriteBase /

# force url to lowercase if upper case is found
RewriteCond %{REQUEST_URI} [A-Z]
# ensure it is not a file on the drive first
RewriteCond %{REQUEST_FILENAME} !-s
RewriteRule (?=([^\/])*(\.htm|\.html|\.jpg))(.*) rewrite-strtolower.php?rewrite-strtolower-url=$3 [QSA,L]

The RegEx (?=([^\/])*(\.htm|\.html|\.jpg))(.*) captures and passes only filename to the php script who makes the real redirect:

<?php
if(isset($_GET['rewrite-strtolower-url'])) {
    $url = $_GET['rewrite-strtolower-url'];
    unset($_GET['rewrite-strtolower-url']);
    $params = http_build_query($_GET);
    if(strlen($params)) {
        $params = '?' . $params;
    }
    header('Location: http://' . $_SERVER['HTTP_HOST'] . '/base/' . strtolower($url) . $params, true, 301);
    exit;
}
header("HTTP/1.0 404 Not Found");
die('Unable to convert the URL to lowercase. You must supply a URL to work upon.');

Example of URL I need to test is:

http://test.com/base/some Folder/some Other subfolder/Some-File-Name.jpg

Needed Result:

http://test.com/base/some Folder/some Other subfolder/some-file-name.jpg

Is there a way to correct things to capture the part of URL that I'm throwing out?

Edit: My entire .htaccess is visible here.

Don't use the exact example. You can get the full path in PHP as well. You don't need to capture the URI. You can use REQUEST_URI in PHP to get the full path. I would do something like this. Just send the full request to php and then handle it there. 

RewriteEngine on
RewriteBase /

#don't do anything if php file is directly requested. 
RewriteRule ^rewrite-strtolower\.php - [L]

# force url to lowercase if upper case is found
RewriteCond %{REQUEST_URI} [A-Z]
# ensure it is not a file on the drive first
RewriteCond %{REQUEST_FILENAME} !-s
RewriteRule . /rewrite-strtolower.php [L]

//php file

<?php
if(isset($_SERVER["REQUEST_URI"])){

    $URI = $_SERVER["REQUEST_URI"];
    $URI = ltrim($URI,"/");
    $parts = explode("/",$URI);
    $filename = array_pop($parts);
    $URI = implode("/",$parts);

    header('Location: http://' . $_SERVER['HTTP_HOST'] .'/'.$URI.'/'.strtolower($filename), true, 301);
    exit;

}
?>
