Your main site needs cookies so that the php generated content is on a cookie domain.

Your static content, e.g. images, does not need to be a cookie domain. So create a subdomain static.example.com and configure it to serve images.

Update Base URL for Static View Files and Base URL for User Media Files in admin -> general -> web -> Base URLs.
