It defines the relationship between the red/green/blue _values_ and their _intensity_ on screen. By supplying it you say: I designed the image on hardware with that gamma value; if you want to see the same image as me and *your* monitor's gamma value is different, you need to adjust the RGB values. However, configuring a system-wide gamma value (and actually having all the software on the system use it) only seems to work on Apple computers. Everybody else just uses the defaults... :-/ > > The same thing happens on Netscape 4. > > Impressive, I didn't think Netscape 4 was any good at displaying PNG > images :-) Amazing, isn't it? :-) Unfortunately, NS4 doesn't support transparent PNGs (not even 1-bit transparency), otherwise using transparency would have been the best solution.
