How can I fill a list with images from an external source?

I have made a JSON file which contains items. Each item also has an image. The JSON file contains image URL's to images online. I want to use these images in my game. Ive made an item class which looks like this:

 public class Items
 {
     public string Name;
     public string Type;
     public string ImgPath;
     public Sprite Image;
 }

The JSON file fills the first 3 strings. The Image attribute should be filled using the URL. I have found solutions to get images from URL using UnityWebRequest. This results in a single image being retrieved, but I cant seem to figure out how to fill my list with images in order to display them in my game.

Ive been stuck on this for a while now, any help will be appreciated.

This is my WebRequests class:

 public static class WebRequests
 {
     private class WebRequestsMonobehaviour : MonoBehaviour { }
 
     private static WebRequestsMonobehaviour webRequestsMonobehaviour;
 
     private static void Init() {
         if (webRequestsMonobehaviour == null) {
             GameObject gameObject = new GameObject("WebRequests");
             webRequestsMonobehaviour = gameObject.AddComponent<WebRequestsMonobehaviour>();
         }
     }
 
     public static void GetImage(string url, Action<string> onError, Action<Texture2D> onSuccess)
     {
         Init();
         webRequestsMonobehaviour.StartCoroutine(DownloadImage(url, onError, onSuccess));
     }
 
     static IEnumerator DownloadImage(string url, Action<string> onError, Action<Texture2D> onSuccess)
     {
         using (UnityWebRequest unityWebRequest = UnityWebRequestTexture.GetTexture(url))
         {
             yield return unityWebRequest.SendWebRequest();
 
             if (unityWebRequest.isNetworkError || unityWebRequest.isHttpError)
             {
                 onError(unityWebRequest.error);
             }
             else
             {
                 onSuccess(((DownloadHandlerTexture)unityWebRequest.downloadHandler).texture);
             }
         }
     }
 }

And this is how I'm able to retrieve 1 image:

 WebRequests.GetImage(url, 
         (string error) =>
         {
             Debug.Log("Error: " + error);
         },
         (Texture2D texture) =>
         {
             Debug.Log("Succes");
             Sprite sprite = Sprite.Create(texture, new Rect(0.0f, 0.0f, texture.width, texture.height), new Vector2(0.5f, 0.5f), 100.0f);
             transform.GetChild(0).GetComponent<Image>().sprite = sprite;
         });
