Cache control by htaccess with condition

I have cache control set by htaccess for all images by this

<IfModule mod_expires.c>
ExpiresActive On
ExpiresDefault A600
ExpiresByType image/gif A604800
ExpiresByType image/png A604800
ExpiresByType image/jpeg A604800
</IfModule>

It works great, but I have also pictures from web camera, which change every 20 minutes. So I need to cache all images except these from camera.

I can write regular expression for those from web camera, they have name which others pictures never can have. But how to put there some condition?

You can disable cache for certain matching files :

<IfModule mod_expires.c>
   ExpiresActive On
   ExpiresDefault A600
   ExpiresByType image/gif A604800
   ExpiresByType image/png A604800
   ExpiresByType image/jpeg A604800
</IfModule>

# disable caching for IMG_20130420_535615.jpg type of files
<FilesMatch "IMG_[0-9]+_[0-9]+\.jpg$">
   FileETag None
   <ifModule mod_headers.c>
     Header unset ETag
     Header set Cache-Control "max-age=0, no-cache, no-store, must-revalidate"
     Header set Pragma "no-cache"
     Header set Expires "Tue, 14 Jan 1975 01:00:00 GMT"
   </ifModule>
</FilesMatch>
