The picture must be Baidu's picture, if not, you can save it in your computer first and then upload it to your Baidu space photo album.
Then, please set it as follows:
1, enter "My I Post Bar";
2. Select "Personal Settings";
3. Select "Signature File Settings" and upload a Baidu picture.
Ps: Baidu will review the newly uploaded signature documents, and the review time will range from a few minutes to several hours. Please be patient.
If the picture is not easy to pass the examination, it will not be inserted.
