 * I have tried everything to make this plugin work, but no luck so far. I’m now
   trying to upload the higher res version of each file but get this error each 
   time:
 * Warning: Cannot modify header information – headers already sent by (output started

 * Sorry for the very late reply. I was busy working on the very last version of
   the plugin, lot of fixes and improvements.
 * Would you mind trying again? Please try the client-side first before experimenting
   with the server-side.

 * That was so long ago, I’ve already moved on to a new theme, which is fully Retina
   compliant.

 * Are we talking about the same thing? The theme generates the images for you and
   all?

 * It’s a Retina-aware theme so it knows to responsively use my double-res images
   without having to rely on wp-retina-2x plug-ins or other hacks.

 * Hey, my plugin is not a hack 😉 Your website is using huge images for every single
   img in your website, that is a trick or a hack and the easiest way to make it
   works for Retina without taking in account performance nor normal users.
 * But I would say that it is fine since you don’t have that many images anyway.
 * You should go with the solution that works for you anyway 🙂 I just hope your
   will not change theme one day, it will be more difficult to upgrade to something
   different (or home-made), or even another Retina-aware theme that will use another
   kind of trick.
 * So you know, there are more and more Retina-aware theme embedding my plugin.

 * Oops didn’t know you were the plugin writer, my apologies! 🙂 It worked great
   on another site! I know I have large images, but no time to optimize. Thanks 
   again for helping me out here, much appreciated!

 * I am glad it works on another website 🙂 By the way, if you like the plugin please
   rate it, I need them ^^ [http://wordpress.org/support/view/plugin-reviews/wp-retina-2x](http://wordpress.org/support/view/plugin-reviews/wp-retina-2x)
