Using a relative link it should be ../Photos/Places%20Visited.kmz (or ../Places%20Visited.kmz)
I don’t know if that will make it work, I don’t use Google maps or Earth.
But the page is seriously malformed. You cannot edit a template unless you understand what all of the code does. To get the page code correct you should post another question in Tiger forum, ask how to make the page correctly.
Thanks for your help.
Unfortunately, that didn't solve the problem.
I'm not an html coder. I'm winging it. The page built and displays satisfactorily (except for Google earth). When that happens, I'm happy !
