Full definition
A CDN distributes resources through a network of servers and caches. It can bring media closer to visitors but does not replace file or theme optimization.
Concrete Shopify example
Illustrative example: use Liquid filters to generate an appropriate image URL instead of hardcoding a Shopify media host.
My take
Check served dimensions and cache headers. An oversized file still costs bandwidth even when served nearby.
