why doesn't the code in $.each run?

$(document).ready(function(){
    var width = 740;
    console.log(width);
        $.each($('.overview img'), function(i, img) {
            width += $(img).width();
            console.log($('.overview img'), width);
        });
        $('.overview').width(width);
        console.log(width);
    });
