I want to change all my URL's with lowercase using `RewriteMap lc int:tolower` in my Apache config file an in my htaccess have this regular expression:

```
RewriteCond %{REQUEST_URI} [A-Z]
RewriteRule . ${lc:%{REQUEST_URI}} [R=301,L]

```

.. and work purfectly! But i have Libraries (with files) and Directories who i don't want to change to lowercase (for example: "Images" with all sub directories or Libraries: "Functions/Liberties/Image/Resize.php") ... how to make it?
I tried with `RewriteRule ^(Images) - [NC,QSA,L]` but don't accept it ... any idea how to make this exceptions?

Thank you in advance and sorry for my english!
