I'm starting with the cluster of buildings at left center making interactive.
my coding will repeatedly use - http://www.centralchristiancamp.org/campmap project/map_html_small/ - and I want to use a variable shortcut in the code.
Will it load faster if I do this?
Thank you,
Please forgive such a basic question, but some of us get more forgetful at age 84

Not sure what you mean by a "variable shortcut" in pure HTML, but there is none. You might as well just code the absolute paths as you have been.
