hiding array of images ?

I have an inventory system that stores all my images into an array but I’m not sure exactly how I would hide / show my array. I know how to hide guiText and images but not something stored in an array. any help ?

Maybe you can make a button, to show the inventory when clicked?
It can be done like this:

showInventory = false;

function OnGUI () { 
    if (GUI.Button (Rect (10,10,100,20), "Show inventory")) 
        showInventory = true; 

    if (showInventory) {
        //show the array here

    if (GUI.Button (Rect (120, 10,100,20), "Hide inventory")) {
        showInventory = false;
    }
    }
}

Hope this helps, cheers!
