This is only tangentially related, but perhaps someone can explain the 
browser issues with PNGs and gAMA chunks:

http://pmt.sourceforge.net/gamma_test/
http://hsivonen.iki.fi/png-gamma-test-results/

Is it a browser issue, or is PNG the problem?  I have heard both arguments, 
but I don't understand exactly what's going on.

Anyone care to shed some light?
