 * I don’t actually know the reason, but it keeps displaying a message like this:
 * **“It seems your server setup does not support headers in .htaccess. You should
   either fix this (install mod_headers) or deactivate the “Enable direct redirection
   to existing converted images?” option. Otherwise the Vary:Accept header will 
   not be added and this can result in problems for users behind proxy servers (
   ie used in larger companies)”**
 * i use openlitespeed web server
