Gui overlapping camera on camera

How would I make it so that a gui texture overlapped a minimap in the corner of the screen (I am using a camera for the minimap). I have the gui texture, but it is on the normal camera layer, and not going above the minimap camera. I don't want the texture all the way ontop of the minimap, but I want it overlapping a little. I have other gui textures appear sometimes, so I deactivated the guilayer on the minimap. What should i do?

Use the UnityGUI instead of a GUITexture. Then you are writing directly to the screen coordinates:

var myImage: Texture2D; // Drag your texture here in the Inspector

function OnGUI(){
