Wood grain texture

I have been reading about using displacement maps to create a wood grain texture on a surface.Can I import a picture of wood grain to use for the map? If so how to I do that ? Rhino has some wood grain textures in the textures but they are very fine grain.I want a pretty obvious thick wood grain to make my box look like it was made from scrap wood.

In the textures panel add a new bitmap texture. Load a wood grain texture of your choice. Use that texture in the object properties displacement page.

Thanks.It worked perfectly!!
