Hans,
I did a "gdalinfo" on the image you attached, it has only
32 colors defined (so it looks "bad"):
Driver: PNG/Portable Network Graphics
Size is 256, 256
Coordinate System is `'
Corner Coordinates:
Upper Left ( 0.0, 0.0)
Lower Left ( 0.0, 256.0)
Upper Right ( 256.0, 0.0)
Lower Right ( 256.0, 256.0)
Center ( 128.0, 128.0)

Are you sure this is the image produced from your new map
file (it's not an old one left over from an earlier attempt
is it)?

Removing DITHER statement I get an "8 bit like" image, as
you can see in the
attachment...
I think I'm going crazy with all this trouble...

Hans,
Try removing PROCESSING "DITHER=YES" from the ORTOFOTO
layer definition. I think it is converting the 24-bit input
raster to 8-bit before it renders it to the 24-bit output
image.

Hans,
That is stange. I've tested mapserver 5.0.0. Beta 4 (it's
the only v5 I've got compiled) and it gives me a 24 bit
color image. What version of Mapserver are you using? Can
you send your entire map file?

Yes, I'm still getting a quantized image using this
statement:
OUTPUTFORMAT
NAME 'AGG_PNG'
DRIVER AGG/PNG
IMAGEMODE RGB
END

So when you remove all the quantize options, you still get a
quantized
image on output? Using something like:
OUTPUTFORMAT
NAME 'AGG_PNG'
DRIVER AGG/PNG
IMAGEMODE RGB
END
