+Obsidian uses wiki-style links for images, like `![[image name.png]]`, which isn't compatible with Hugo out of the box. Here's how I automated it in a Gitea Actions workflow:
+- I find all used image references in `.md` files.
+- For each referenced image, I update the link in relevant `.md` files like `![image name](Images/image_name.png)`.
+- I then copy those used images to the blog's assets directory while replacing white-spaces by underscores.
+
 ### Step 4: Gitea Actions for Blog Repository
 
 The blog repository contains the full Hugo site, including the synced content and theme.
