I'm trying to scale images that have a width greater than 100. I'm using the code below, but it scales images that are even below 100px... What am I doing wrong?

if($(".image-attach-body")) {
    if($(".image-attach-body a")) {
    $(".image-attach-body a").each(function() {
                var width = $("span span img").width();

                if(width > 100) {
                    $("span span img").cjObjectScaler({
                            destObj: $(".image-attach-body"),
                                method: "fit",
                });
                }
    }); 
    }
}
