Redirects
Redirect Image Permalink to Event on Timeline (Found to me more useful to have a "landing page" (Image's Permalink Page) for images)
Redirect Image URL to Event on Timeline (down side is WGET fetches HTML code instead of JPG)
Redirect Timeline Event (AKA Post) Permalink to Event on Timeline
Yoast
Redirecting sitemap_index.xml to a different file
Other Coding
Timeline Express: Scroll delay and adjustment to bring Event on Timeline into view
To Do
functions.php: Add a script to every page (per the existing Post example) for navigation to raw URL of image
Use code further down in functions.php file for Post Navigation and use something similar in the image.php file.
