The variable [pagePath] is used to for pathing to image files.
Default is for pages in a single subfolder.
To change the value for higher/deeper folder structure, reset the value in the page itself 
in the first editable section after the call to this script.

For example: For pages in the root folder, use the template [root_about_page] which resets 
this variable to blank.
