I have this in the fence section of a markdown file for a blog post:
heroImage: "../../blog-images/post1.webp"
this breaks because it tells me I need to provide a remote url or import, but I don't think I can import inside a .md file. What's the right way to do this? The theme by default references the same image in the public folder, but I want to reference a different image for each blog post, preferably taken from src/content/blog-images

Hi @dense gyro. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:
You're correct that you can't use import inside a markdown file. However, you can use relative paths to reference images from your project's src/ directory in your markdown files. This is done using the standard markdown syntax for images: !**alt** (src).
For example, if you have an image called post1.webp in a directory called blog-images within your src/ directory, you can reference it in your markdown file like this:
!**Blog Post Image** (../../blog-images/post1.webp)
This will allow you to move your images from the public/ directory to your project src/ where they will now be processed and optimized. Your existing images in public/ and remote images are still valid but are not optimized by Astro’s build process.
If you require more control over your image attributes, you can use the .mdx file format, which allows you to include Astro’s <Image /> component or a JSX <img /> tag in addition to the Markdown syntax. You can add support for MDX to Astro using the MDX integration (https://docs.astro.build/en/guides/integrations-guide/mdx/).
Please note that there have been some issues reported with image paths in markdown files, as discussed in these GitHub issues: #9863 (https://github.com/withastro/astro/issues/9863), #5928 (https://github.com/withastro/astro/issues/5928), #1188 (https://github.com/withastro/astro/issues/1188), #5295 (https://github.com/withastro/astro/issues/5295), #6880 (https://github.com/withastro/astro/issues/6880), and #6194 (https://github.com/withastro/astro/issues/6194). The Astro team is aware of these issues and is working on improvements.

@ember imp Will this work in the header (fenced) section of md file or only in the body?

Let me check the knowledge base for you. One moment! :books:
The image reference using markdown syntax !**alt** (src) is typically used within the body of the markdown file, not in the frontmatter (the fenced header section).
The frontmatter is usually reserved for metadata about the page, such as the title, description, and other properties. It's not designed to render markdown or HTML content.
If you want to reference an image in the frontmatter, you would typically provide the path to the image as a string, like this:
---
title: My Blog Post
heroImage: "../../blog-images/post1.webp"
---
Then, in your layout component (an .astro file), you would use this metadata to render the image. Here's an example:
---
import { Markdown } from 'astro/components';
const { heroImage } = Astro.props;
---
<img src={heroImage} alt="Hero image" />
<Markdown>
{Astro.props.content}
</Markdown>
In this example, heroImage is a prop that gets its value from the frontmatter of the markdown file. The image is then rendered using an <img /> tag in the layout component.
Please note that this approach requires that your markdown files are processed by Astro, which means they should be located in the src/pages/ directory or a subdirectory thereof. If your markdown files are in a different location, you may need to adjust your project configuration or file structure.
