Hi edgeman, yeah take the contents of the zip and upload to where the pp-inc.php is (and all the rest) then in the photopost admin you can alter the info "Full path to Header Include file" and simple put there : header.html
the "Full path to the Footer include file" you say cannot be edited or blanked out? - i don't think even you could break that!
- i jest, clear your browsers cache and reload the admin pages.
