My Plattform is Debian etch Linux amd64

Sorry, what I said was not fully correct. It doesn't work with Amaya9.54 
either. But some time ago, it worked. I think that it doesn't work any 
more since the last software update I made.

The guys from debian made some changes, one of them is that g++ reports 
the cast from void* to int as an error on 64 bit plattforms. (I think 
it was a warning before) This problem has already been mentioned in the 
thread "64-bit clean code". I don't know what other things they 
changed. Perhaps I can find out ...

The problem with the PNGs does not turn up on Debian etch i386, so it 
must be some amd64 related problem.

Other applications that use libpng work fine.

I checked out Amaya right now (2007-07-13) the latest revision (HEAD) 
from CVS (I had to replace an (int) with a (long int) in 
thotlib/dialogue/attrmenu.c to get it to compile, 
but this should not be related with my problem.)
The same problem turns up in releases 9.55-2 and 9.54

It does not depend whether the images are referenced by CSS, by 
html:img, or whether one views them directly.

Tell me if you need more information. Crazy problem ...
