For a site with a very large number of images that are served by a CDN, is it better for that CDN to be a subdomain of the main domain (cdn.example.com) or a completely different domain (exampleimages.com)?
Does it make any difference? I'm thinking mainly about ranking the images in Google Image Search, but also about any effect on ranking the pages in Web search.
(I'm not considering the subfolder approach (example.com/images/) for infrastructure reasons, and also because I understand there is an SEO advantage to the page due to page speed if the pages are served from a different connection from the browser.)
