Try this:

    using UnityEngine;
    using System.Collections;
     
    public class Resume : MonoBehaviour {

        bool paused = false;
     
     
        void OnGUI (){
            // Only show the menu if the game is paused:
            if (paused) {
                bool clicked = GUI.Button (new Rect (500, 15, 100, 50), "PauseImage");
                // If the player clicked the button, resume the game:
                if (clicked) {
                    Resume();
                }
            }
        }
     
        void Update(){
            // If the player presses Escape, pause or resume the game:
            if (Input.GetKeyDown (KeyCode.Escape)) {
                if (paused) {
                    Resume();
                else {
                    Pause();
                }
            }
        }

        void Pause() {
            Time.timeScale = 0.0f;
            paused=true;
        }

        void Resume() {
            Time.timeScale = 1.0f;
            paused=false;
        }
    }

You don’t need OnMouseDown because you’re using OnGUI instead.
