For instance, if I create a level 1 header that looks like:
<h1 src="/example.png">This is a header</h1>
The text "This is a header" would be replaced with the image that's
located at /example.png. However, if /example.png returns a 404 error,
the text would be displayed instead.
Opera supports this with css extensions.
 This is supported in the CSS specs properly, via the content property.
 *[src] {
  content: attr(src,url);
}

If I understand things correctly, your example seems a little bit confusing to me. The *[src] selector selects elements with a src attribute specified, which does not apply to <h1> (if valid HTML5)

*[data-my-src] {}
<h1 data-my-src="">
