Pause game while GUI instructions displayed?

Hi!

I have a script attached to my GUITexture that appears a few seconds into my game, and disappears again in 5 seconds.

I was wondering if there is a way to pause the game while this GUI is displayed? It would make the game run a whole lot better.

Thanks in advance.

 public class TestScript : MonoBehaviour {
         private GUITexture myGUITexture;
         [SerializeField]
         private float delaySeconds = 1.0f;
         [SerializeField]
         private float showForSeconds = 1.0f;
         
         void Awake() {
             myGUITexture = GetComponent<GUITexture>();
         }
         
         void Start() {
             ShowImage();
         }
         
         public void ShowImage() {
             StartCoroutine(ShowImageTimed(delaySeconds, showForSeconds));
         }
         
         IEnumerator ShowImageTimed(float startDelaySeconds, float showForSeconds) {
             Debug.Log("In coroutine.");
             yield return new WaitForSeconds(startDelaySeconds);
             Debug.Log("Enabled texture.");
             myGUITexture.enabled = true;
             yield return new WaitForSeconds(showForSeconds);
             Debug.Log("Disabling texture.");
             myGUITexture.enabled = false;
         }
     }
