Yes, it is possible.

You can use the_content hook and assign your own filter to this hook.

Then you should (that is the part when things get a little bit messy) parse and replace content of that post.

So for example you can do it like so:

function my_the_content_filter($content) {
  $content = str_replace('<h2 ', '<img src=""...><h2 ', $content, 1);
  return $content;
}

add_filter( 'the_content', 'my_the_content_filter' );

It says error :( Fatal error: Cannot pass parameter 4 by reference in – Chymmi Jul 4 '13 at 14:12
    
in...? The rest of this message is important. – Krzysiek Dróżdż Jul 4 '13 at 14:39
    
Parameter 4 of str_replace is number of replaced tokens, not number of replacement. Remove it, or use some variable here. (Cannot edit post to fix this, as "Edit must be at elast 6 charaters"). – PeterM Mar 17 at 9:48
