How do I add a texture to an empty in 2.54?

I’ve been trying to add the wood texture to an empty in 2.54 so I can rotate it, but I can quite figure it out. Any tips?

You can not add materials to an empty but you can add textures(I’m not sure why). You can, however use an empty to project a texture onto an object that has a material.

In 2.5 go to your texture that is applied to an object (not the empty) and click the Coordinates drop down. Choose object then pick or type in the name of the empty you want to use as a projector. The empty projects along the Z-axis so you will have to make sure the empty is aligned to your object correctly. After that you can scale and rotate the empty to scale and rotate the texture.
