Set custom 404 Error for static contents

[afshin.m]

Hi,

 

i want to set a custom (and empty) 404 error for my static contents like CSS, Gif, Jpeg etc.

i found this code :

 

<FilesMatch "\.(css|png|jpg|jpeg|gif|bmp|swf|flv)$">
   ErrorDocument 404 error-404.txt
</FilesMatch>

 

But it not worked for images that located in sub folders, it works for images that located in the root folder and where my .htaccess file located.

 

Please help, thanks
