How to use jQuery live() for img onload event?

I want to run some code when an image is loaded. Also, I'd like to do it unobtrusively (not inline). More specifically, I want to use jQuery's live() function so it will happen for any dynamically loaded images.

I've tried:

<img class="content_image" alt="" src="..." />
<script>
    $('.content_image').live('load', function() {
      alert('loaded!');
    });
</script>

In addition to load, I've tried onload, and onLoad. When I replace with 'click' all works as expected so I know it's not some interfering bug.

I haven't been able to find a list of available event types for the live() function, so for all I know, it may not be possible.
