If you can separate-out the images to a specific URL (img.domain.com)
and put them all in the same directory, you can use NGINX to serve them.
Of course, the actual transfer-speed will not increase much - but
latency will go down to the absolute minimum.
And latency is what makes a page appear "fast" or "slow" to customers.
