Exclude folder from redirect

WordPress redirects everything in wp-content if accessed directly to 404 with the following:

<IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$   - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> 

What I want to do is not redirect the contents of a sub folder example.com/wp-content/uploads/event/images/

Any ideas how I can achieve this?
