Cloudimage can download your origin images/files from any server or storage bucket over HTTP/HTTPS/FTP. Setting up an external storage is optional and you can use Cloudimage with your origin image URLs as shown in the introduction.
If the images are not publicly available, you have to configure your storage containers and set authentication parameters. If you are filtering access to your image storage by source IP address, contact us to obtain a list of the Cloudimage resizing servers.
You can set up an external storage in the Storage section in the admin panel by using the Connect External Storage button.
