[mapserver-users] shp2img working, mapserv not

[Oliver Christen]

open your .dbf file and look at the paths inside (the file is binary but the path are readable), the paths must be something mapserver can find based on your mapfile SHAPEPATH, otherwise Mapserver will not succeed to access the related images.
I would advice using the -write_absolute_path option (if thats not already the case)
