Answer 1

Remember, if you want to change the styles of the element and/or change the img source, just do something like this:

<img
  src={'original src url goes here'}
  alt="example"
  onError={(e) => {
     e.target.src = '/example/noimage.png' // some replacement image
     e.target.style = 'padding: 8px; margin: 16px' // inline styles in html format
  }}
/>

Hope it helps!

You have onError={this.onError()} with instant function call. It should be either onError={this.onError.bind(this)} or onError={() => this.onError()}.
