How do you download image to UI.Image?

Question

T$$anonymous$$s is as far as I got

 IEnumerator downloadImg (string url){
         WWW www = new WWW(url);
         yield return www;
         Texture2D texture = new Texture2D(1, 1);
         www.LoadImageIntoTexture (texture);
 
         Sprite sprite = Sprite.Create (texture, new Rect (0, 0, texture.width, texture.height), new Vector2 (0.5f, 0.5f));
         imagePrefabClone.GetComponent<Image>().sprite = sprite;
     }

But for some reason the sprite is not getting set. Any ideas?

T$$anonymous$$s got it working

 IEnumerator isDownloading(string url){
         // Start a download of the given URL
         var www = new WWW(url);            
         // wait until the download is done
         yield return www;
         // Create a texture in DXT1 format
         Texture2D texture = new Texture2D(www.texture.width, www.texture.height, TextureFormat.DXT1, false);
         
         // assign the downloaded image to sprite
         www.LoadImageIntoTexture(texture);
         Rect rec = new Rect(0, 0, texture.width, texture.height);
         Sprite spriteToUse = Sprite.Create(texture,rec,new Vector2(0.5f,0.5f),100);
         imageToDisplay.sprite = spriteToUse;
 
         www.Dispose();
         www = null;
     }

You can do it easily with Davinci
The library has a simple usage and supports Unity UI.Image and 3D model textures.

 Davinci.get().load(imageUrl).into(image).start();

Hope t$$anonymous$$s helps!

Why would you use an external library when it can easily be done with Unity?

It's not an external library. It has a simple c# script that written for unity and has a lot of benefits and features like fading animation and process callbacks. Take a look at its that page. You don't have to reinventing the wheel, cause 'time' is matters ;)

I t$$anonymous$$nks helpful for you.

//here is the code

string WebUrl , ServerUrl; public Image Web_image , ServerImage; Texture2D tex; WWW Link;

 IEnumerator LoadImageInternet()
 {
     tex = new Texture2D(4, 4, TextureFormat.DXT1 , false);
     Link = new WWW (WebUrl);
     yield return Link;
     Link.LoadImageIntoTexture (tex);
     Web_image.sprite = Sprite.Create (tex, new Rect (0, 0, tex.width, tex.height), new Vector2 (0, 0)); 
 }

 //Button Event
 public void LoadFromInternet()
 {
     WebUrl = "https://upload.wikimedia.org/wikipedia/commons/d/dc/Cats_Petunia_and_Mimosa_2004.jpg";
     StartCoroutine (LoadImageInternet ());
 }

Now in 2021 Unity recommend t$$anonymous$$s code that is more efficient and also worked perfectly.

 //PlayGamesPlatform.Instance.GetUserImageUrl() Used to get player Image from Google Play Games
 
 using UnityEngine.Networking;

     private IEnumerator GetPlayerImage(string url)
         {
             UnityWebRequest www = UnityWebRequestTexture.GetTexture(url);
             yield return www.SendWebRequest();
     
             Texture2D myTexture = DownloadHandlerTexture.GetContent(www);
     
             Rect rec = new Rect(0, 0, myTexture.width, myTexture.height);
             Sprite spriteToUse = Sprite.Create(myTexture, rec, new Vector2(0.5f, 0.5f), 100);
     
             playerImage = spriteToUse;
         }
