In general, it's not considered a good thing to trade a little effort
on your part for a greater (and probably duplicated) effort on our part.
That said, you wouldn't have found what you were looking for anyway
because there is no way to do that in the current official version of
POV.  I think you can do it with the image_pattern patch that's 
included in both Nathan Kopp's UVPOV (http://nathan.kopp.com/patched.htm)
and in the Superpatch (http://www2.fwi.com/~parkerr/superpatch)
