[mapserver-users] The browser can't display the rendered image

Wed Nov 19 12:37:12 PST 2008

Attila,
It is strange, because the IMAGEURL in mapfile is correct, but the html
generated from the script report <IMG
SRC="c:/ms4w/tmp/ms_tmp/4923f091_c84_0.jpeg">, i.e. a local path and not a
url.
The correct tag should be something like <IMG
SRC="/tmp/ms_tmp/4923f091_c84_0.jpeg">

Are you sure the mapfile of the script is the same you are editing?

ciao .................pg
