With Cloudimage, we do not store your images permanently. You need to store your images on your with your own hosting provider and the assets have to be accessible via HTTP(S).
When you provide a URL of an image, our servers fetch and cache it. Then they apply the requested transformation, optimize the image and deliver the image to your customers via CDN.
Filerobot is our Digital Asset Management solution. You can find out more about the storage of Filerobot in the Upload and Manage section in our documentation.
You can upload images by using the Asset Hub.
