Tue Oct 2 05:54:25 EDT 2007

hi, first thanks for your replay
but after the change the same problem:

here are my configurations:
-----------------------------
config.php:

$aszGMap = array (
         'title' => 'geoland.at',
         'path' => '/usr/share/ka-map-1.0-20070205/htdocs/geoland_test.map',
         'scales' => array( 600000, 250000, 120000, 75000, 30000, 10000 ),
         'format' =>'JPG'
         /* Sample authorized_users entry. See auth.php for more details:
          * ,'authorized_users' => array('popplace' => array('user1',
'user2'),
          *                              'park'     => array('user1')
          */
 );
------------------------------
part of my mapfile:

But still, the image is not displayed correct!
further more, when i set the imageformat "JPG" in the Orthophotos Layer, the
Orthophoto will be loaded
(172.21.18.45/ka-map/title.php?map=gmap&t=-46336&l=155904&s=10000&g=Orthophotos&i=jpg)
but not displayed any more.

is there anything wrong in my mapfile?
the orthophotos are ok when i disply them in a Software like Pain or call
the mapfile with the DesktopGIS qGIS but not with ka-map?
