In the page at http://www.worldchessrating.com, the png chess board images do
not display properly. The black pieces are white and the text at the top is
unreadable. 

This works with IE6. 



Reproducible: Always

Steps to Reproduce:
1. Go to http://www.worldchessrating.com/522981136.html?470765106845647
2. See incorrect image
3.

Actual Results:  
Black pieces at the top of the chess board image are not black.

Expected Results:  
Displayed the Black pieces as black.

I also tried this on Linux with Mozilla 1.3b, Phoenix 0.5, Konqueror, and
Galeon. None of the Linux programs I tried displayed the image correctly. This
most likely is a website problem, but, I felt it best to send this to you guys
to make sure.

thanks - Warren

The image is actually set transparent on the black pieces, with a fallback
background that's black.

Now IE does not support PNG 8-bit alpha channels, so it falls back to the black.
 Mozilla _does_ support png transparency, so we show the black pieces as
transparent... and the image is on a white background.

I suggest contacting the site and letting them know that any browser that can
actually render PNG images correctly will fail to show their images "as
intended"....
