Unseen by Alpha Channel?

I have a background plate that I want to render but I don’t want it in the image’s alpha channel. How do I set this to be “unseen by alpha” in Blender? I’m using 2.6x.

I’m going to bump this… really need to know the answer if someone has it. If Blender does not do this, let me know so I can stop searching.


Ok… I’m going to write this off as “Blender cannot do this”.

New to blender was looking for this with those exact worlds only to found this, guess it is no longer a mystery but just in case some else is looking for it:
