OpenGraph image

[hazy dust]

@valid moon in a Markdown file, I have the following file structure:

---
layout: "@layouts/MarkdownPostLayout.astro"
title: TIDAL "Wrapped" 2023
author: Steve Frenzel
description: My favorite tunes from the year Tina Turner died, Twitter turned X and mass shootings in the U.S. reached a new all-time high.
pubDate: 2024-01-07
slug: tidal-wrapped-2023
tags: ["music", "tidal"]
image:
  url: ../../images/blog/5/thumbnail-tidal-wrapped-2023.png
  alt: "Tidal Wrapped 2023"
---

When referencing the image url via frontmatter.image.url the image is not correctly displayed, while the alt text of it is correct. I also want to use the same image for the OpenGraph image for social previews but again, it's not working.

Here's the code for the blog post layout:

---
import type { FrontmatterProps } from "../types/FrontmatterProps";
import Layout from "@layouts/Layout.astro";
import SkipLink from "@utils/SkipLink.astro";

interface Props {
  frontmatter: FrontmatterProps;
}

const { frontmatter } = Astro.props;

const dateFormatted = new Date(frontmatter.pubDate).toLocaleDateString(
  undefined,
  { year: "numeric", month: "long", day: "numeric" },
);
---

<Layout
  description={frontmatter.description}
  thumbnail={frontmatter.image.url}
  title={frontmatter.title}
>
  <div id="markdown-wrapper">
    <header>
      <SkipLink />
      <h1>{frontmatter.title}</h1>
      <div>
        <p class="author-and-date">
          {frontmatter.author} - {dateFormatted}
        </p>
        <a href="/blog">Back to blog</a>
      </div>
      <img src={frontmatter.image.url} alt={frontmatter.image.alt} />
    </header>
  </div>
</Layout>

When moving the image for OpenGraph to the public folder, what changes would I need to make in my blog post layout in order to make it work?

Hi @hazy dust. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

Based on the information provided in the extracts, it seems that the issue you're facing is related to the location of your images. Astro's Image component processes images that are located in the src/ directory of your project, not the public/ directory. Images in the public/ directory are not processed or optimized by Astro’s build process. They are considered as remote images and are just copied over as-is into the dist directory during the build process.

If you want to move your OpenGraph image to the public directory, you would need to adjust the path in your frontmatter and layout file accordingly. However, please note that this image will not be processed or optimized by Astro.

Here's how you can adjust the path in your frontmatter:

image:
  url: /images/blog/5/thumbnail-tidal-wrapped-2023.png
  alt: "Tidal Wrapped 2023"

And in your layout file:

<Layout
  description={frontmatter.description}
  thumbnail={frontmatter.image.url}
  title={frontmatter.title}
>
  <div id="markdown-wrapper">
    <header>
      <SkipLink />
      <h1>{frontmatter.title}</h1>
      <div>
        <p class="author-and-date">
          {frontmatter.author} - {dateFormatted}
        </p>
        <a href="/blog">Back to blog</a>
      </div>
      <img src={frontmatter.image.url} alt={frontmatter.image.alt} />
    </header>
  </div>
</Layout>

Please note that the path to the image is now relative to the public directory.

For more information, you can refer to the Astro documentation (https://docs.astro.build/en/guides/images#update-your-markdown-mdx-and-markdoc-files) and the GitHub issues (https://github.com/withastro/astro/issues/4349) related to this topic.

@valid moon How do you recommend to handle the thumbnails for blog posts when using Markdown and using Astro?

[valid moon]

Let me check the knowledge base for you. One moment! :books:

Astro provides several ways to handle thumbnails for blog posts when using Markdown. Here are some recommendations based on the information provided in the extracts:

1. Use Standard Markdown Syntax: You can use the standard Markdown !**alt** (src) syntax in your .md files. This syntax works with Astro’s Image Service API to optimize your local images and authorized remote images. For example:

---
title: My Blog Post
image:
  url: ../../assets/my-thumbnail.png
  alt: "Thumbnail for my blog post"
---

And in your Astro component:

<img src={Astro.props.frontmatter.image.url} alt={Astro.props.frontmatter.image.alt} />

This will automatically optimize the image for you. More details can be found in the Astro documentation (https://docs.astro.build/en/guides/images#images-in-markdown-files).

2. Use Astro's <Image /> Component in MDX Files: 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. This requires adding support for MDX to Astro using the MDX integration (https://docs.astro.build/en/guides/integrations-guide/mdx/).

3. Use Content Collections' image() Schema: If you're using Astro's Content Collections to manage your blog posts, you can use the image() schema to handle images. This allows you to optimize the images and use them in your Astro components. More details can be found in the Astro documentation (https://docs.astro.build/en/guides/assets/#update-content-collections-schemas).

Remember, the <img> tag is not supported for local images, and the <Image /> component is unavailable in .md files. If you need these features, consider using .mdx files instead.
