Changing Images Dynamically

Hello everyone!

I'm trying to dynamically change a RawImage
Here's my code bellow, doesn't seem to work
Can't find anything online
I should also add that I'm a new Unity Dev

Thanks in Advance!

Code (CSharp):

1. {
2.     public RawImage img;
3.     private string url = "https://i.redd.it/bz504sn6ree51.png";
4.     //private int imgHeight = 250;
5.     //private int imgWidth = 250;
6.     //private int posX = 10;
7.     //private int posY = 50;
8.     private int counter = 1;
9.  
10.     // Start is called before the first frame update
11.     void Start()
12.     {
13.         StartCoroutine(ChangeImage());
14.     }
15.  
16.     IEnumerator ChangeImage(){
17.         yield return 0;
18.         UnityWebRequest www = UnityWebRequestTexture.GetTexture(url);
19.      
20.         Debug.Log("Here2, url: "+url);
21.         yield return www.SendWebRequest();
22.  
23.         img.texture = DownloadHandlerTexture.GetContent(www);
24.      
25.         // TextureScaler.scale(img.texture,imgHeight,imgWidth);
26.     }
27.  
28.     void Update()
29.     {
30.         if(Input.GetKeyDown(KeyCode.Space)){
31.             if(counter % 2 == 0){
32.                 url = "https://i.redd.it/bz504sn6ree51.png";
33.             }else{
34.                 url = "https://i.redd.it/rgce12mplle51.jpg";
35.             }
36.             counter++;
37.             Debug.Log("Here");
38.             StartCoroutine(ChangeImage());
39.         }
40.     }
41. }

 

Why are you setting img = null in line 31 above?

 

Oh I was trying to reset the image, scratch that
