The CI seems to fail in citing pics, I've observed some md files merged and see that pics in the same directory of md file can be cited, but mine has a "image/" and it cannot recognize it. If it's the problem of astro, plz tell me and I'll adjust the file structure and make pics and mds in the same directory.

eg.
-- example.md (cited images/somepic.png)
-- images
|
-- somepic.png
The astro will report an error in such an example above

按照之前仓库的情况，相对地址的picture应该是没问题的，你看看是不是用了绝对地址？另外，建议你先只放少数核心文件（10-20篇左右）

@mudongliang 我看了那个报错，是相对的地址，不知道为什么就是不行

I've mistaken the global email address, so the licence check is always pending. I'll close this and create another one.
