How to export texture to Maya?1?

Hy!..I´m in a big trouble in here:. I want to export my all project (human head) made in maya ,that i exported to zbrush, where i made the uv maps, the polygon painting and the texture, but now i want to export it all to Maya again. But i just get the mesh, the uv and the color painting imported in Maya with GOZ…not the texture…and i need the texture like bump maps…to get a realistic human texture like i made in zbrush.
Someone can help me?:. I dont know how to do to get the texture map exported with everything into Maya, showing the bump map texture.

Thanks to all
