Computer screen animation by texture

Create a C script named ImageFromDirectory and add following code

 using UnityEngine;
     using System.Collections;
     
     public class ImageFromDirectory : MonoBehaviour
     {
         //A texture object that will output the animation
         private Texture texture;
         //With this Material object, a reference to the game object Material can be stored
         private Material goMaterial;
         //An integer to advance frames
         private int frameCounter = 0;
         
         //A string that holds the name of the folder which contains the image sequence
         public string folderName;
         //The name of the image sequence
         public string imageSequenceName;
         //The number of frames the animation has
         public int numberOfFrames;
         
         //The base name of the files of the sequence
         private string baseName;
         
         void Awake()
         {
             //Get a reference to the Material of the game object this script is attached to
             this.goMaterial = this.renderer.material;
             //With the folder name and the sequence name, get the full path of the images (without the numbers)
             this.baseName = this.folderName + "/" + this.imageSequenceName;
         }
         
         void Start ()
         {
             //set the initial frame as the first texture. Load it from the first image on the folder
             texture = (Texture)Resources.Load(baseName + "00000", typeof(Texture));
         }
         
         void Update ()
         {
             //Start the 'PlayLoop' method as a coroutine with a 0.04 delay
             StartCoroutine("PlayLoop", 0.04f);
             //Set the material's texture to the current value of the frameCounter variable
             goMaterial.mainTexture = this.texture;
         }
         
         //The following methods return a IEnumerator so they can be yielded:
         //A method to play the animation in a loop
         IEnumerator PlayLoop(float delay)
         {
             //wait for the time defined at the delay parameter
             yield return new WaitForSeconds(delay);  
             
             //advance one frame
             frameCounter = (++frameCounter)%numberOfFrames;
             
             //load the current frame
             this.texture = (Texture)Resources.Load(baseName + frameCounter.ToString("D5"), typeof(Texture));
             
             //Stop this coroutine
             StopCoroutine("PlayLoop");
         }
