select your image plane and open its attributes window. select the "render stats" section and toggle off the primary visibility.

hi chasey let me tell you there is no primary visiblity option in render stats for image plane ..but i am sure there has to be an option to hide this image plane in render...help plz

Actualy there isnt, and a image plane is either visible or not. Tough if you justs want reflection and refraction there are other means to do it!

joojaa..can you let me know how we achieve that

altough I am not Joojaa, You can always put some refrlection color in material.
Aletrnatively, You can use poly/nurbs plane with same image, parented to same camera, and there turn primary visibility off.

Hey, you can create your own image plane from scratch in this manner:

1) create a nurbs plane that matches the size and aspect of your camera film aperture (you'll need to convert from inches to cm, assuming you're working in cm)
2) move your camera to world zero.
3) position the plane in front of the camera.
4) move the plane N units away, where N is the focal length of your lens in mm.
5) group the plane under your camera (or some node under the cam grouped at the camera "nodal point").
6) Texture map plane. Scale group as needed. The image plane will scale correctly.

Had to do this several times on a production, so I wrote an expression, so that you can move the plane anywhere (like beyond objects that are supposed to reflect it !), and it gets rescaled automatically. I am not at work here, but if anyone needs it, just ask.
It's a simple "tan" thing...
