Replacement "#APP_FILES#" only exists in the context of an apex session. It is parsed by the APEX engine at runtime. It doesn't make any sense in an html file or email outside of APEX.
When someone opens the email in his email client, APEX is not in the picture. So if an image is referenced in the body of an email, the image needs to be available to the email client in order to be rendered - typically within an intranet (in which case when the user logs into the intranet they will be able to image seen in the mail), or—if desired—on the public internet. Either way, a fully qualified url is required.
