Your RewriteCond is only allowing index.php, images and robots.txt and sends everything else to index.php
This is one I use:
Code:
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteCond $1 !^(index\.php|gallery|img|pdf|css|js|flash|font|user_guide|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ index.php/$1 [L]
</IfModule>
