Describe the bug

file: _includes/media-url.html
line number: 18
code snippet:

{% assign url = include.subpath | default: '' | append: '/' | append: url %}

issue: if include.subpath is nil or empty string, and url is a relative path, e.g. path/to/file , the code will force overwrite url to absolute path /path/to/file , which will leads image url error to plugins like jekyll-postfiles.

Steps To Reproduce

see Describe the bug

Expected Behavior

don't try to force overwrite user's path type(absolute or relative).

Environment

• Ruby: ruby 3.3.7 (2025-01-15 revision be31f993d7) [x86_64-linux-gnu]
• Jekyll: jekyll 4.4.1
• Chirpy: jekyll-theme-chirpy (7.3.1)

Anything else?

A relevant issue, I suppose:

I am getting an error (ERROR '/chirpy-test/chirpy-test/assets/images/posts/20190808/devices-mockup.png' not found.) on my /_posts/2019-08-08-text-and-typography.md because of this update: 1bac96a.

It might be helpful to provide an example of relative path usage.

@kungfux with relative path,

• review markdown static contents (picture, pdf...) locally while editing by using vscode or typora.
• avoid error prone uri prefix to the /assets/... path, which is repeated several times in all posts.
• make jekyll plugin works: jekyll-postfiles; jekyll-asset-path-plugin
