WP Offload Media Tweaks
Create a /amazon-s3-and-cloudfront-tweaks/ folder in /wp-content/plugins/ and simply drop the
amazon-s3-and-cloudfront-tweaks.php file into it. Then go to the Plugins page in your WordPress dashboard and activate it.
amazon-s3-and-cloudfront-tweaks.php file and take a look at the
__construct() function. You will notice that all the calls to
add_filter() are commented out. So, at the moment the plugin does nothing even though it's activated. To enable a filter, simply uncomment the appropriate
add_filter() line, but please make sure the corresponding function further down in the plugin's source has been adjusted to fit your needs.
Most of the examples in the plugin's handler functions will need editing before they can be used.
