Apologies in advance if this is a stupid question!

We use nginx for our sites, and have it installed on eight or so web servers using the official Yum repository. However we'd like to use the image_filter functionality, but it doesn't seem to be built in by default with the Yum-installed version.

I was wondering if there was an additional package I can install via Yum to enable that functionality? Similar to how PDO can be enabled in PHP using the package php-pdo?

If not, is there a chance this will be available in the future? Or do I just need to compile nginx myself?

Thanks!
