The error message you're seeing suggests that the dimensions of the image are missing. In Astro, if your image is located inside your src folder, you should import it instead of directly using the path.
However, since you're dealing with dynamic content (blog posts), you might not be able to import images in the traditional way.
Astro is planning to introduce a new astro:assets module in v3.0 which will replace the existing @astrojs/image integration. This new module is currently available under an experimental flag and is recommended for new Astro projects. If you're using a version of Astro prior to v3.0, you might want to consider enabling the experimental flag to use assets as an image solution. You can learn more about this in the Astro Assets Guide (https://docs.astro.build/en/guides/assets/).
If you're using Astro's image integration components, you can refer to the Astro Image Guide (https://docs.astro.build/en/guides/images/#astros-image-integration) for a full list of component attributes and usage details.
If you're still encountering issues, it might be helpful to check the path of your images and ensure they're correctly referenced in your code. If your images are stored in a public directory, you might need to update the link to the relative URL.
Here's an example of how you might use images in Astro:
---import { Image } from '@astrojs/image/components';import localImage from "../images/brand/logo.png";import rocket from '../images/rocket.svg';---
<Image src={localImage} alt="The Astro Logo" /><img src={rocket} alt="A rocketship in space.">
In this example, localImage and rocket are imported from the local images directory, and then used as the src attribute in the Image and img elements respectively.
