Uploads your wordpress attachements to S3 with an option CloudFront distribution
It works, alright! However, it puts media.merchantcircle.com in between you & your S3 account. It listens in on port 443 and will not allow you to connect to your S3 account unless you're connected to media.merchantcircle.com first!
I would STAY CLEAR OF THIS PLUGIN! Unless you want to give, whoever the jerk off is who wrote this, access to your S3 account!
This plugin should be removed from WordPress!
