WWW.texture with a wildcard in the URL

Hello everyone,

If you have a webapge with a url to an image that is always slightly changing, is there any way creative way to display said image in Unity without knowing the exact URL.

For example, if * was recognized as a wildcard character in Unity:

 using UnityEngine;
 using System.Collections;
     
     public class example : MonoBehaviour {
         public string url = "https://www.google.com/images/srpr/logo**.png";
         IEnumerator Start() {
             WWW www = new WWW(url);
             yield return www;
             renderer.material.mainTexture = www.texture;
         }
     }

Thank you very much!
