Answer by krtek for reformating an RSS feed with jQuery

Try this code :

$("li.rssitem").each(function() {
    var target = $(this).children("h3");
    $(this).find("img").each(function() {
        $(this).remove();
        $(target).before($(this));
    });    
});

I didn't tested it, so I'm not sure it will work out of the box, but hopefully you'll be able to modify it to suits your needs.
