maybe something like this:

 using UnityEngine;
 using UnityEngine.UI;
 using System.Collections;
 
 public class ChangeAlpha : MonoBehaviour
 {
   Image image;
 
     IEnumerator Start()
   {
     yield return new WaitForSeconds(2);
     Color c = image.color;
     c.a = 1;
     image.color = c;
   }
 }

You can change the Image opacity like this way...........

public class opacity : MonoBehaviour {

 public Image img;
 // Use this for initialization
 void Start () 
 {
     StartCoroutine ("Wait");
 
 }

 IEnumerator Wait()
 {
     yield return new WaitForSeconds (2.0f);
     img.color = new Color (1.0f,1.0f,1.0f,1.0f);
     StopCoroutine ("Wait");
 }
 

}
