[ka-Map-users] Black tiles when using JPEG

[R. Ortner]

Hi,

i have a .shp layer type raster made with gdaltindex for my orthophotos.
when i change the imageformat to jpeg (in the config.php and in the layer
metadata section of my orthophotolayer) i get only black tiles!
when i remove the entry for the imageformat i get displayed the orthophotos
in png 8bit and thats not very useful.

is there a bug or something i have to change?

config.php entry: 

$aszGMap = array (
         'title' => 'geoland.at',
         'path' =>
'/usr/share/ka-map-1.0-20070205/htdocs/orthophotos.map',#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')
          */
 );
