thks - yeah, I saw that about the controller location.   Problem is if 
you use the map in more than 1 view, then you have the same image 
folders in multiple locations, not good though a hackable solution.   So 
it would be better to modify the Utils.js - I noticed that is available 
under the /libs directory so I guess that should be installed.   I'll 
play around with that (noting that Rails sees image mime types and goes 
to the /images folder so I think the location needs to be there).    It 
gets worse - if you have a background image in your map - Rails will see 
it as an image mime-type and look for it under /images.  If you have a 
kml file - Rails simply sees it as an external file and sees it under 
the /public folder.  And it gets worse if you have an SVG file, firefox 
wants to see it as an xml file type but Rails does something with the 
mime-type and I'm not sure what.
