You haven't told me this... :-( 

Ok, now I saw what was wrong. The picture was saved with 6 bit per gun
precision while the orginal was 8 bit per gun. I changed it now. But there
is still a grey background (0x808080) which should be transparent (I don't
know how to change this; I can only change the RGB values). But it should
be no problem this time, because the other affected grey colnum 25 has
(0x838383).
The transparent color (0) is of course noted in the tRAN chunk of the PNG
so this all shouldn't matter.
But note that in oposite to the orginal cities.xpm there is an additional
color (a darker red) so it now uses 32 colors instead of 31 (including the
transparent color)

BTW
Is there a easy portable xpm creating program (preferable without GUI) which
I can port to the amiga?

In case the PNG is still weird (please tell it then) I will restore the
old .xpm ASAP.

I'm sorry that this ever has happened.
