Before you go crazy with my procedure, one change, change the Diffuse color to black, specular color to black and leave the Ambient color alone (should be black by default).  Wish I could go back and edit it.

Hmm, Angel, gonna give your procedure a try too.  Haven't tried another procedure, placing a texture node image directly into the reflections color channel and perhaps adjusting the u and v size.  Strange how one idea leads to another---Jan
