As Bob said, you should use "hf_grey_16 on" when generating the heightfield with
Povray. With png output, you have to use +fn16 to get 16 Bit grayscale output.
IIRC the black parts in the heightfield are a known problem, there were some
posts about that in the past:

Try this one:
#version unofficial MegaPov 0.5;
global_settings
{
hf_gray_16
ini_option "+FT"
ini_option "-w256" // change this
ini_option "-h256"
}
// ----------------------------------------
camera
{
orthographic
location <0.0, 5, .0>
look_at <0.0, 0.0, 0.0>
right 1*x
}
plane
{
y,
-1.0
texture
{
pigment
{
image_map
{
png "g:\ray\maps\river_01.png" // change this
once
interpolate 4
}
}
finish
{
ambient 1
}
rotate 90*x
translate <-0.5, 0, -0.5>
}
}

Thanks, it works.
However, I still can't understand what's the problem with MY source.
Further more, this is what comes out when I try to use that output in
the HF scene:

Don't know what you're doing over there Lewis but your posts are in some
strange format, I have to run them through MetaMail before viewing, but
the post with the image in it didn't have that problem. Maybe it's the
character set that you're using or something like that.

I don't have a problem either but I think Steve is using some kind of
Unix and probably doesn't have Hebrew support. Of course he doesn't
need it to read Lewis' posts as they are in plain English but Lewis'
newsreader seems to be thinking differently :)
And then of course I could be all wrong, as more and more often
happens (age?).
