Image map + bump map. And rework with photoshop.

This is a well known problem with povray : normals!

In other soft you can use displacement map and you have real
elevation, just by using the bump map. With povray, this is 
more tricky because you need isosurface or heightfield. Which
is more difficult. I already saw some attempt to create wood
with hieghtfield, the result was more or less good but it took
several weeks for the guy to get a "good" result so...
With a displacement map it take you no more time that with the 
present bump map.

Thanks a lot. This was just the purpose of these images : 
test texture :).
