I modeled this kitchen a few weeks ago, rendered with BI. Now I converted it to Cycles, adding new textures and modifying certain objects. I'm still trying to debug the .blend since some images are magnifying its size and they are no longer used under Cycles.
So far I don't know how to proceed to eliminate such unused images, but I'll keep on trying.
When I get positive results, I'll edit the .blend. Sorry for that. Here your are, friends.
NICE
