How to Use Amazon S3 With WordPress

1. Open your Web hosting control panel. Navigate to 'Manage DNS Server Settings.' Create a new entry. Give it a name that you will remember. Under type, select 'CName.' Under value, enter 'S3.amazonaws.com.' including the period. This will point your Web hosting to Amazon S3 storage.
2. Go to the WordPress admin by entering 'http://www.yourwebsite/wp-admin.' From the left panel, click on 'Plugins.' In the Plugins window, select 'Install Plugins.' Download and install the 'Amazon S3 for WordPress' plugin. When it is finished installing, click 'Activate this Plugin' (see Resources).

3. Go to the 'Amazon S3 for WordPress' plugin settings. Enter in the AWS Access Key ID and secret key provided to you when you sign up for Amazon S3 storage space.
4. Select the bucket you wish to pull files from in the 'Use This Bucket:' menu. Buckets are used by Amazon S3 as a way of organizing files. All files that you wish to use with WordPress should be dropped into one bucket.
