[mapserver-users] Raster Aerial photos

[Iris Schnegg]

Hi,

I am trying to include 80 aerial photographs.  The size of each of the 
photos is circa 25 MB.  I converted them from 24 bit jpg pictures to 8 
bit tif images with image alchemy.  When I include one of the pictures 
in the mapping file the image is in a pretty good quality.  When I 
include five or more pictures, the quality of the pictures deteriorates. 
 I get white and gray pixels in the images where they don't belong.  It 
almost looks like the red channel is missing.  When I view the pictures 
in Corel Photo paint, the colors seem to be all right.

Can anybody help me out?

Thanks,

Iris
