How to overlay an image over the camera

I have 2 cameras which render side to side. However, I want a png to overlay over each camera’s result. I tried GUITexture but I guess I didn’t set it up correctly and it doesn’t show. How do I do this?

If you need an image to cover both camera views, I’d suggest creating a third camera with a render depth that is higher than both of the first two cameras, and with its clear flags set to depth only. You’ll want to remove the GUI Renderer component on the bottom two cameras. If you call GUI.DrawTexture with a rect the size of the screen, it should work.
