This problem has come up before for me. I had to manually (or using search/replace in an HTML editor) replace all instances of EXAMPLE.COM with MYTESTSERVER.COM/EXAMPLE for sake of links/images not being broken (This includes any values for HREF or SRC properties--especially these types, actually).
The site was made in 2012... it does include template files (WordPress theme I developed painstakingly over the course of 5-6 months). The template files aren't really what I'm concerned with... it's the countless references to the old domain that was used within the "post" files...
This was an "Online Literary Journal", so there's enough supporting graphics spread throughout the individual posts' code to make me want to find a script to stick in the header.php or footer.php which will change this all over for me on each browser load, without me having to alter the code much (at least for the time being while this is still an "archived" client site)... THANKS!
NOTE: I am NOT actually using any kind of <BASE> coding... as in building links through the structure of the site's code based on a single instance of a base href. This site was one of my first WordPress projects, and furthermore one of my first "dynamic-like" sites... so I also did not utilize WordPress' php function of bloginfo()... WISH I HAD NOW LOOKING BACK!
**also now i realize that using PHP code within posts isn't the easiest thing to do... nor was it then, so the links were coded as static.
