Baidu pictures cannot be loaded online, but can they be displayed locally? Causes and response methods

In web browsing, you may encounter this situation: the same HTML code cannot display Baidu pictures online, but they can be displayed normally after downloading them locally. This article analyzes the causes of this problem and provides some possible solutions.

Here is a sample HTML code snippet:

<tr class="ant-table-row ant-table-row-level-0" data-row-key="157941061">
<td class="ant-table-cell">
        276b206633e200641d3f9ddabc657888</td>
    <td class="ant-table-cell">image</td>
    <td class="ant-table-cell">
        <div> ✅</div>
    </td>
    <td class="ant-table-cell">
        <div>
            <div>
                <div class="ant-image ant-image-error" style="width: 200px;"><img  class="ant-image-img lazy" src="/static/imghw/default1.png" data-src="https://img.php.cn/" alt="Why can't Baidu pictures be loaded online, but locally can? Is there any solution?" ></div>
            </div>
        </div>
    </td>
</tr>

The image link in the code contains token parameters, which is the mechanism by which Baidu image server prevents link theft. User feedback that even if the browser's content blocker is turned off, the image is still unable to load, and prompts to block access requests for cookies or storage space.

The root cause of the problem lies in the anti-theft link mechanism of Baidu Picture Server. This mechanism verifies whether the source of the image request is legitimate by checking Referer header information or token parameters. If the request source is not identified as an authorized source (for example, accessed directly from an image link, rather than from an internal link from a Baidu website), the server rejects the request.

Although it is not recommended to bypass the anti-theft link mechanism, if you have to resolve this issue, you can try the following methods (but please note that these methods may be invalid or violate the terms of use of Baidu Images):

• Modify Referer: Some browser plug-ins or tools can modify Referer information in the HTTP request header to simulate requests from within Baidu website.
• Remove token parameter: Try to delete @f_auto?token=9239a3fdc3e8e54f5cfb422db8ce1578 part from the image URL, but this does not guarantee that the image will be loaded successfully, and Baidu may change its anti-theft link strategy at any time.
• Local cache: Download the image locally, and then modify the HTML code to use the local image path. This method is suitable for small amounts of images, but not for batch processing.

Again, respecting copyright is not recommended to bypass the anti-theft chain mechanism. The above methods are for reference only, and the actual effect depends on the specific anti-theft link strategy of Baidu Picture Server. We recommend that you seek formal access to pictures.
