Example 1.9: Interactive Maps and the Browse Mode NOT WORKING

Mon Jan 7 14:10:17 EST 2008

Hi, I suggest you look at the example map file again and compare the WEB 
object with the one in your map file.  In particular look at the 
keywords IMAGEPATH and IMAGEURL.  The difference between these two 
keywords is mentioned (probably not very clearly) in 
http://biometry.gis.umn.edu/tutorial/example1-7.html.

Cheers!
