leverage browser caching not working (Image Show GK4 fault?)

Hi...
I have some "leverage browser caching" issues and I am suspecting that is is "Image SHOW GK4"
I have used the following code in my .htaccess file:

<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType text/css "access plus 2592000 seconds"
ExpiresByType text/css "access plus 604800 seconds"
ExpiresByType text/javascript "access plus 604800 seconds"
ExpiresByType application/x-javascript "access plus 604800 seconds"
ExpiresByType application/javascript "access plus 604800 seconds"
ExpiresByType image/png "access plus 2592000 seconds"
ExpiresByType image/x-icon "access plus 2592000 seconds"
ExpiresByType image/jpeg "access plus 2592000 seconds"
ExpiresByType image/gif "access plus 2592000 seconds"
ExpiresByType image/jpg "access plus 2592000 seconds"
</IfModule>


but when i test with pingdom it still says that i need to leverage browser cache for a lot of images inside the "image" folder. Usually this code works and sets an expiration date for most jpg files.
Most of the problem jpg's are used by "Image Show GK4". Of course I am not sure that this is the problem.

Can you help?!?!

Just solved it... It wasn't "Image Show GK4" fault... it was the hosting provider that served files through NGINX...

I changed the configuration and now works wonders!

Hi
