	The gamma chunk in PNG images has given me nothing but trouble.
Every browser, every program, seems to (over)compensate for gamma 
in a different way.  The answer is to make sure the png file has
no gamma chunk in it.
	Here is what I do ..
	Render/create image to Targa (tga) file.  Open said Targa
file in gimp.  Save as a PNG from gimp.  In the file save dialog, 
make sure that the "save gamma" box is NOT checked.  Save.  You
have just written a png that contains no gamma.  End of problem.
