I want to be able to set a fallback img when loading of an image fails, eg on 404. In html you can do this by setting the onerror attribute. Currently In my own code I need to interpolate strings to be able to build the onerror attribute. Would be nice if Blazorise can do this for me.

Current onerror building

<Image Source="@ProfilePicture" onerror="@m_fallbackPicture" />

@code { 
   private string m_fallbackPicture;

   protected override void OnParametersSet()
   {
       m_fallbackPicture ??= $"this.src='{Assets.Get(@"img/DefaultAuthor.png")}'";
   }
}

Proposed Blazorise API

   <Image Source="@ProfilePicture" FallbackSource="@Assets.Get(@"img/DefaultAuthor.png")" />
