The images available here have already been gamma corrected somewhat (using a gamma of 1.5) such that they look reasonable on our local displays. If your display has a gamma of less than 1.0, you will probably need to darken the images somewhat (using a gamma of less than one); if your display has a gamma of more than 1.0, you will probably need to brighten the images somwehat (using a gamma of greater than one).
If you're using xloadimage, this can be done with the -gamma command line option. If you're using xv, this can be done interactively using the "Color Edit Box". See the documentation for your image viewer for more information.
