Image URLs not correct

I must confess I don’t know much about the way S3 works but your plugin is not working correctly out of the box for me. Maybe I’m doing something wrong?

Here is my configuration:

1. I created an S3 bucket through the plugin interface.
2. Object path: wp-content/uploads/
3. No Cloud front Domain Name.
4. Enabled – Copy files to S3 as they are uploaded to the Media Library
5. Enabled – Point file URLs to S3/CloudFront for files that have been copied to S3
6. Enabled – Remove uploaded file from local filesystem once it has been copied to S3

My uploaded files are being transferred to my S3 bucket. Media files are being deleted from uploads folder on my server. Image URLs in content are being replaced but the images are 404ing. If I right click the broken image and try opening in a new window I get and XML doc that contains the following

<Error>
<Code>NoSuchBucket</Code>
<Message>The specified bucket does not exist</Message>
...
</Error>
