I must admit i tended to say "oh, come on, this hardly has anything to do
with the OS". I guess that's still right ;-)), but I don't guess any longer
the html code isn't right or the link targets don't exist an so on.

Only thing I can think of is a keepalive issue. please change

KeepAlive On 

in your httpd.conf to

KeepAlive Off

and see if it helps. please report, i'm really interested what actually
happens and what the real reason is. turning off keepalives is just a
workaround if it works at all. 

The strange thing: when I force a relad of the one image (in Opera using
"show image" in the context menu) _this_ image shows up just fine _both
times_. If I reload the whole page they are gone again. strange strange.
would somehow second the keepalive guess. would even make more sense if
you'd use ipf with s/t like "pass in proto tcp from any to [loc ip] port =
80 keep state" or something likely, the state entry might be dropped to
quick or such. It's still strange anyhow.
