        if(width > maxWidth){
            ratio = maxWidth / width;
            $(this).css("width", maxWidth);
            $(this).css("height", height * ratio);
            height = height * ratio;
        }
        var width = $(this).width();
        var height = $(this).height();
        if(height > maxHeight){
            ratio = maxHeight / height;
