Baidu can set up five sets of signature files at most, and the total size cannot exceed 5M.
If you are all moving picture signature files, exceeding the limit may be automatically compressed.
Also note that when quoting the picture link of Baidu Space Album, don't quote the URL of the thumbnail, but open the original picture to get the URL link.
Good luck! If you have any questions, ask them. This is helpful and I hope to adopt them.
