The admin page for setting the markers for home or locations ends right before the markers area where the text inputs are for entering the urls to be used for home and locations images. Those fields did not exist again on the page until I deleted the database record containing the home marker that I had tried to change. What I did to create this minor disaster was try to use a relative path there. I assumed I could use Janitor to clear out all the settings, but it didn’t work, so I had to search and delete the record myself with some mysql statements.
