Depends on how you set up the plane, if you set it up in the camera settings or whatever, I have no idea how any of it works. But the best way I think to set it up is to use a poly plane with the image on it as a textured lambert.

To do so, just make a poly plane, click it's instance in the sidebar thingy on the right... Forget what its called atm. Then resize it via the hotboxes to a scaled down size of the image (example; 500x400 image = 50x40 plane) After this, open hypershade (Window -> Rendering Editors -> Hypershade) Create a new lambert in there, then hold control and drag and drop the image for the plane into the hypershade window and on to the lambert.

After that, create a new layer, which you seem to have figured out, add the plane to the layer, and you'll be able to hide it, or delete it, or whatever, whenever you want.

Horrible, horrible guide. But maybe if someone rewrites it it could work.

Didn't read this myself, but it seems it may help more.
