I am preparing to change the main site of my multisite. And I am confused by the multiple urls and file structures of several images from two years ago and before.
For example one image is available on two different image url structures:
http://hornaffairs.com/tg/2015/01/23/tplf-victory-to-repeat-poverty/image-tplf-40th-anniversary-official-banner-jpg/ (on this link, it looks like a post with comment space)
Again it is also found on two thumbnail urls:
Again it is available inside the relevant article:
All these are indexed by Google!
I don't know how this happened. But I am confused on how to fix it.
When I change the subsite domain path, which of these url addresses should I redirect? What should I do with the rest?
