Ok I made some maps, and I love your little tool.
I found the Thestra and Qalia maps worked perfectly, however the Kojan map didn't work at first. I changed the Kojan references from "C3" to "C4" in both the XML and the map filenames, and this got it working for me.
I also found the text label for the chunk on the minimap came up green, which is definitely not the default colour. I changed it to black, but I think it should actually be white by default?
I added an XML file for the MiniMap - you might want to include one of these in the zip file (along with that "Maps" directory).
And finally I changed the name of the map from "Jadrin" to "Info". This is just a case of substituting the name throughout the XML, but perhaps you could write something into the tool to allow the user to choose a custom name for their map?
If you download my InfoMap beta mod you can compare to your original and see the changes I made. (See this thread: http://www.vginterface.com/forums/showthread.php?t=1652
