假设您使用的是 jQuery，您可以在 DOM 就绪函数中为您的图像创建水印，并使它们的位置绝对并相对于图像进行计算。

<script type="text/javascript">

    // Watermark image, change the src with your image's url
    var watermark = '<img src="watermark.png" border="0" style="border:none; background-color:transparent; position:absolute; ';

    // Position relative to image inside:
    var insideTop = 20;
    var insideLeft = 50;

    $(document).ready(function () {
        $("img").each(function (ix, el) {
            var top = $(this).offset().top + insideTop;
            var left = $(this).offset().left + insideLeft;
            var imgWatermark = watermark + 'top:' + top + 'px; left:' + left + 'px;"/>';
            $("body").append(imgWatermark);
        });
    });

</script>

如果您有将带有水印的图像和不带有水印的图像，请向将带有水印的图像添加属性 class="withWatermark"，并将脚本中的 $("img") 替换为 $("。带水印”)。

<img src="myimage.jpg" class="withWatermark" />

$(".withWatermark").each(function (ix, el) {
