title: How to make a picture appear at the center of the player camera when an object is clicked?
body: <p>So I'm building a virtual gallery where the user is able to walk around and see pictures.
  Now when he clicks on a picture, I want that picture to pop up take up the screen and also display some metadata about the picture, maybe read a text file related to the picture? How do I do this? I'm very new to Unity so any help will be greatly appreciated.
  I'm using the below code to detect the gameobjects.</p>
  <pre><code>    using System.Collections;
      using System.Collections.Generic;
      using UnityEngine;
      using UnityEngine.Events;
      
      public class ObjectClicker : MonoBehaviour
      {
          public LayerMask interactableLayermask = 6;
          UnityEvent onInteract;
          void Start()
          {
      
          }
         
      
           void Update()
          {
              RaycastHit hit;
              if(Physics.Raycast(Camera.main.transform.position, Camera.main.transform.forward, out hit, 2, interactableLayermask))
              {
                  Debug.Log(hit.collider.name);
              }
          }
      }
  
  ```[I want to click on them and that image pops up and takes up the screen and displays some metadata about it.][1]
