Change the Markers in the Map

Question

I have been working on trying to change the markers on the map page from the little green smug guy to my own image.

I have this working on a regular HTML page, but I am struggling a bit getting it working on Smug

<script type="text/javascript">
    $(function () {
            $('img[src="http://cdn.smugmug.com/img/maps/greenmarker.png"]').attr('src', 'http://www.joeywashburn.com/photos/i-jRdxVqD/0/O/i-jRdxVqD.png');
    });
</script>

I first tried it in the header section and it didnt work, but then I thought since Smug has to go out and get the information for the maps, maybe it had not pulled down greenmarker.png yet, so I moved it to the footer, still no luck.

Any ideas?
