# Connecting storage bucket

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 - [Welcome to Cloudimage](/readme.md).

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 IP addresses, [Contact us](https://admin.cloudimage.io/contact-us/) to get help with configuring [proxy](https://admin.cloudimage.io/project/settings/proxy) for Cloudimage to request origin images over the specified proxy and have all Cloudimage requests coming from the same IP address. 

You can set up external storage in the *Storage* section in the admin panel by using the *Connect External Storage* button.
