Reflects the image colors? Hum... not that I can see, I get the
same icon with 4 boxes from black to white no matter what
image I open (ECW, mrsid, since GeoTiffs do not open).
Do you have the algorithm that generates the icon handy? A svn
pointer?
Showing the predominant colors from the raster symbolizer is a smart
idea and much more relevant than a generic icon (especially a generic
that assumes a particular icon set is being used on the client side).
Does the benefit outweigh the technical heft?

Does not geosilk provide something?
It does, I included it in the previous message (it's the bluish
checkerboard one).
As Jody noted, GeoSilk does provide an icon for raster:

Unfortunately, that doesn't address your concern about scaling. It
also assumes that the client is using GeoSilk throughout—which is a
safe assumption for GeoServer and GeoExt, but not much further.
