Cloudinary

 Cloudinary  is a hosting and management service for images and video which can be used as an image proxy.

Marty McGuire
uses Cloudinary as a resizing and cropping image proxy for media that he uploads to his site. The process works in three parts:
 * a micropub media endpoint running at  accepts uploads and then serves the uploaded file back as-is.
 * a static site powered by Hugo recognizes URLs for files at  and re-writes them into proxied URLs through Cloudinary.
 * Cloudinary fetches the original file from, performs any resizing and other transforms such as face-finding and cropping, and caches the result.

Example flow:
 * 1) Marty creates a photo post with Indigenous.
 * 2) * In the background, Indigenous has micropub media endpoint support. It uploads the photo to  and gets back the URL to the new image:
 * 3) * That URL is in the  property for the new post.
 * 4) Marty's site rewrites the   URL so that the request will be proxied through Cloudinary.
 * 5) ** This will restrict the resulting image to 960px width, and will crop the image in "fill" mode.
 * 6) ** More info about URL parameters in the Cloudinary image transformation reference docs.
 * 7) When a browser visits the resulting post it requests the image from Cloudinary, which will fetch it from , transform, and cache it for future requests.
