How to reverse search author by image in Sina Weibo?

When browsing on the web, sometimes you will see that other websites will have thumbnails of Sina Weibo's external links. In social media intelligence investigations, there may be a need to find the uploader of a Sina Weibo image that originated from another website.

In fact, every Sina Weibo image contains information about the uploader. It is very easy to find the uploader's information through Sina Weibo images.

Moreover, even if the user deletes the image, we can still look up his homepage as long as we have the image URL.

Take the following picture as an example, first copy the image address.

https://wx2.sinaimg.cn/mw690/008a9zetly1gjb1hk904tj31hc0u0np9.jpg

The last 8 digits after the last slash, i.e. "008a9zet" is the identification code. And this identification code is in hexadecimal.

We can find the uploader by simply converting this identification code to decimal and adding it to the Weibo user URL "https://weibo.com/u/xxx".

Here you can use the following tool for conversion.

https://tool.lu/hexconvert/

Now we have got the decimal code as 7479106405. Then add this identification code to the Weibo user URL.

You will get the URL as:

https://weibo.com/u/7479106405

Next visit the URL to access the target user's Weibo.
