Mark,

I believe that the ability to change paths across the wiki from when its 
hosted as a file (Timimi and Other savers), or a 
bob/tiddlyServer/TiddlyDesk Top node etc... at different IP address/DNS 
name, folder and Port should have some *defacto* if not djoure 
(https://onlinelaw.wustl.edu/blog/legal-english-de-factode-jure/} standard 
as it is a common need. 

We could actually automate this to some degree using the $:/info tiddlers 
to generate a here path, ie relative to where it is currently hosted, but 
allow this to be varied in one or more groups eg images etc...
