Simple WP Retina

Seamlessly switches out images on Retina and other high pixel density screens with @2x versions.

The switch happens server side saving on HTTP requests.

No action is required on your part other than to activate it and to regenerate your thumbnails with the Regenerate Thumbnails plugin.

Plugin automatically:

• Detects a HighDPI screen such as a Retina display
• Detects all image sizes added using add_image_size() and adds @2x versions.
• Replaces featured thumbnails and content images with the @2x versions for users with HighDPI screens.
