The small images are definitely not usable.

They definitely are here. Only on a few of them have I felt the need to
use Google Earth to zoom in on part of the image that shows something
unusual.

I can make out some detail on
the screen, but as you say they are almost black. Mainly though, the pixel
resolution in the images is much coarser than if you go to the Google Earth
location. I think they should probably have emphasized that in the
instructions, since some people may be trying to search the small images.

I'm sure many are and in my experience that is perfectly acceptable.

One thing I found useful, in both the presented images and the Google Earth
view, is to load the image into photoshop and enhance the contrast; on my
screen the Google Earth image is also very dark and lacks contrast.

Sounds like you might benefit from adjusting your monitor:

If it is an LCD flat panel you may want to experiment with the angle you
view it from too as that can have a marked influence on the brightness
and contrast.
