Question

Goal: Load an image with a dynamic source. If no image is found, then load a placeholder image instead.

This should demonstrate what I\'m trying to

Answer 1

The following approach also works if you want to handle the error in you class:

In your template:

<img [src]='varWithPath' (error) ="onImgError($event)">

In your class:

onImgError(event) { 
    event.target.src = 'assets/path_to_your_placeholder_image.jpg';
}

Answer 2

<img class="thumbnail-image" src="getImage()" alt="...">

getImage():string{  //I don't know how would you handle your situation here. But you can think of it.

  if (this.validImage) // I don't know how would you manage validImage here.
  {
     return this.validImagePath;
  }

   return this.placeholderImagePath;
}
