Hide/Unhide GUITexture Help!

I have a group of GUITextures that is inside a parent named “Pop_Up_Box”
that consists of yes or no option “yes” and “no” has their own GUITexture, and a background Guitexture for the window

All I want to know is that, is there a way to hide all those GUITextures inside the parent “Pop_Up_Box” at the same time?

if yes how can we do it?

Pseudocode:

function OnGUI()
{
  showTextures = GUI.Button (.. "Show GUITExtures"....
  if (showTextures)
  {
    GUITexture(.....
    GUITexture(....
    etc
  }
}
