完整的互联网 URI | http://example.com/avatar.png
站点内的地址 | 将头像放置**_主题_**目录下的 source/uploads/ （新建 uploads 目录若不存在）配置为：avatar: /uploads/avatar.png或者 放置在 source/images/ 目录下配置为：avatar: /images/avatar.png

Search the documentation for the table describing avatar locations and compare it with the issue's `theme/source/uploads` and `source/images` paths. Correct the inaccurate wording so the documented placement and configuration values match, then review the rendered documentation to confirm the table is clear.
