Can't get texture to show up on my object

[Nova]

Try checking your material, by using "RMB>Edit Material" in the outliner. Make sure it has your texture in the diffuse. If it doesn't, use "RMB>Pick up image" on your texture and then use "RMB>Drop picked object" on your material and select "Diffuse".
Then, select your object in body mode and go "RMB>Assign to selection" on your material in the outliner.

EDIT: Also, make sure you're using a shader that can display textures, in case you changed it. Hemispherical Lighting works for this. Just though I should mention this, as I've made that very mistake in the past.
