Appending texture?

I downloaded a leather ball texture from the blender library. Its a blend file. How do I change the texture on a belt in one blend file to the texture on the downloaded file? If I append - file - object etc nothing happens. ie how do i get te leather texture into the texture box??

In the append dialog, you should be able to select materials or textures to append from another file. Append the material, the texture will come with it. I’m not sure whether the object brings the materials along for the ride.
