if there's a hosted image from a facebook domain (e.g. a like button), unless that image is loaded after consent is given, facebook can already associate that users' IP address with having visited that web site by nature of sending the image over. in other words, facebook is tracking pre-consent

This just leads to a bunch of questions: where an image is loaded from FB by a site, who is the data controller? Surely it's the primary site, not FB? In that case, then is FB a data processor (and subject to more restrictions)? If FB is a controller in its own right then how does FB gather consent in this case?
