Display GUI texture on specific variable value?

I want a GUItexture to appear when objectColor == a number but i don't know the display on GUI script. This is javascript and i have the textures i want saved in my asset folder. I need to know how to access them and display them on the screen at a certain position. This is the script i have controlling the value of the variable.

  if (Input.GetButtonDown(">"))
             objectColor = objectColor + 1;
  if (Input.GetButtonDown("<"))
             objectColor = objectColor - 1;
         if (objectColor >= 2)
             objectColor = 2;
         if (objectColor <= -2)
             objectColor = -2;
