Defender and Si-Captcha

Hi there,
i noticed an error when using Defender and the Si-Captcha plugin (https://de.wordpress.org/plugins/si-captcha-for-wordpress/) together.
Defender creates an .htaccess in wp-content which deactivates access to all .php files. But Si-Captcha needs access to
/wp-content/plugins/si-captcha-for-wordpress/captcha/securimage_show.php
to display the catcha images.
I fixed that with manually changing the .htacces in wp-content to:

## WP Defender - Prevent PHP Execution ##
<Files *.php>
Order allow,deny
Deny from all
</Files>
<Files securimage_show.php>
Allow from all
</Files>
## WP Defender - End ##

Hope this helps
