The first step in working with imgix is to create a Source, which connects imgix to your image storage. There are currently four types of Sources:

• Amazon S3: Connects to an existing Amazon S3 bucket with its own credentials.
• Google Cloud Storage: Connects to an existing Google Cloud Storage bucket with its own credentials.
• Web Folder: Proxies content from a given domain (or a subfolder on the domain).
• Web Proxy: Can proxy any valid image URL.

The requirements for each Source type vary. Sources may also contain additional configuration options such as default parameters, default images, cache-control headers, and cross-origin request information.

Note: When naming your Source subdomain, only a single level is allowed. For example, images.imgix.net will be allowed, but my.images.imgix.net will not.
