Using htaccess or a php file to cache only static files

Question

I am looking for a way to implement cache control & expire headers to my images/css/js files. I looked for tutorials & only found ways to add cache control using file extensions. The code below is the one got from http://betterexplained.com/

<FilesMatch "\.(jpg|jpeg|png|gif)$">
Header set Cache-Control "max-age=604800, public"
</FilesMatch>

This sets all the images of the mentioned extensions to be cached for one week. However I don't want all the images to be cached, because there are some images that are upload by the users. I only want my static images eg: logo, icons used for buttons to be cached. It would be great if someone could point out a way or a tutorial on how this could be achieved.

Answer 1

or again you could just move the htaccess file in the folder that will be cached and save the user image in another :D
