It doesn't seem to work very well with phong. I guess the phong
highlights don't work very well alongside the fake highlights that are
already painted on the image map. To get it to work with phong I think
that the texture map would have to be recreated without highlights and
there'd probably need to be a normal map 

One thing that does help a little is turning up the lighting so that the
painted highlights become fully white rather than grey, but then the
dark parts of image tend to get a bit too bright.

I first used the histogram function Stretch and then applied a
shadow/midtone/highlight filter with shadow:10 midtone:50 highlight:50.
It was done in Paint Shop Pro 5.

There should be a way to lower the upper number without sacrificing
quality.
