CodePen Embed - HTML only image fallback

<p>
  Below an image is embedded in an 'object' tag. If that image is not loaded correctly (e.g. inexistent image) the 'img' inside it is loaded instead.
</p>
<object data="https://not-existing-image.jpeg" type="image/jpg">
  <img src="https://picsum.photos/250" alt="" />
</object>
