Can anyone provide some help on how to define the link structure to add a background map that is stored on a local PC drive.
e.g. file://D:/tiles/$z/$x/$y.jpg does not work for a TMS exported map.
Thank you in advance, Rolf
I think it won’t work because of cross-origin policy. If it were, any site could browse your computer when you were browsing the Web, just like in the old IE days 
An http server on the localhost wouldn’t work either, I think.
An http server should probably work, I think, but you might need to access it via IP address and/or put a crossdomain.xml file there.
