I need an 2 or 3 example images that highlight the gamma differences
between Mac and windows.   I need these to show my students why it is
so important to check web graphics created on a Mac that will be
displayed on PCs.

Hi sherpaj-ga:

Thanks for the interesting question!

Since you are obviously knowledgable about *why* these gamma
differences occur (heck, you're teaching others about them), I won't
go into the reasons for these annoying color differences in pictures
on Macs and PCs. :-)

I was able to find several illustrative examples of the gamma
difference. Each of these images come on pages that might also have
some interesting technical/theoretical information you might want to
build into your teachings (depending on how advanced your students
are).

comparison nonetheless. 

I hope these examples help you out in your class! Please let me 
know if you need any clarification of this answer before you 
rate it. 

Thanks.
