The CM Ad Changer plugin supports the use of WordPress Ad Server Cloud Storage, which enables to serve banners from a cloud storage system like S3 directly to external client side websites where they are published. This is an popular and highly convenient feature because it helps to optimize and speed up the delivery of your banners and save space on your website, while making it easy for client side administrators to find and access your banners.
Its soooo simple! To start serving ad banners from the cloud, setup the cloud storage option for each of the advertising campaigns you wish to use this feature with. You can also specify the cloud storage path, public access and connection credentials.
After setting up cloud storage, upload the banners that the Ad Changer uses and remember that you will be uploading them again to the S3 cloud storage by the following path used by the server-side plugin.
Next, create a bucket on S3 which will be used to hold your banner images.
Make sure that the path of this bucket is inserted into the Ad Changer campaign settings, as shown above.
Last, make sure to set your banner images to public so the CM Ad-Changer server can serve them from the S3 cloud storage to the websites that have the client plugin installed.
