How do I load an image via a URL in Unity?

I recently worked on the development of a Unity plugin. Where it was necessary to load images from a URL on a web server. In the end, the solution is rather simple and has the advantage of being asynchronous (which has almost no impact on performance).

Here's the resulting code:

public async Task<Texture2D> DownloadImage(string url, Action<Texture2D> callback)
{
    UnityWebRequest www = UnityWebRequestTexture.GetTexture(url);
    www.SendWebRequest();

    while (!www.isDone)
    {
        await Task.Yield();
    }

    if (www.result != UnityWebRequest.Result.Success)
    {
        Debug.Log(www.error);
        return null;
    }
    else
    {
        Texture2D texture = ((DownloadHandlerTexture)www.downloadHandler).texture;
        callback(texture);
        return texture;
    }
}

There you go! Hope it can help you.
