html - 禁止从 html 页面下载图像

Question

假设有一个 html 页面包含一些图像。

我们希望禁止从用户端下载图像。

这可能吗？

我是否需要使用 javascript或添加一些attributes在<img>标签？

我当前的代码是

       <td><img src="images/handmade (1).jpg" class="img-responsive" alt="" /></td>

    </tr>
  </table>

有什么技术可以防止图像下载吗？

不，这是不可能的。此处说明:https://graphicdesign.stackexchange.com/a/39464/24086

For all intents and purposes, this is downright impossible. You can disable right click, but people can still view the source code of your page (by adding view-source: to the URL in Chrome, or just using a browser menu) and find the URL. You can use a CSS background-image instead of HTML , but people can still use their browser's inspector (F12 for most browsers) and find that element's CSS properties. You can engineer some crazy thing that you think will work, but at the end of the day, the user has to download the image in some way to see it. If the user is completely unable to download the image, he/she won't even be able to see it in the first place! No matter what you do, nothing will prevent a simple glance at a network traffic monitor or the "Network" tab of your favorite browser's developer tools.
