Cycles Renderer

I am pretty new to cycles renderer and have playing around with it for a little while. I was wondering how do you make a picture go straight to the matieral output (I am using the node editor). I noticed that the color output on the picture is yellow while the input on the material is green and I noticed that all the shaders outputs are green. So does that mean that you only a shader can input into the output. And how would I go about getting a picture to come straight to the output not just the color

If you’re new to the Cycles engine, I suggest you start with the Cycles manual, because explaining everything on a forum can be a pretty long process.

thank you, hopefully these will help
