#How to import multiple images
cold cosmosBOT
To import multiple images in Astro, you can use the import.meta.glob function which returns an object of all the image paths inside a specified folder. You can then use these paths to display the images using the <Image /> component from astro:assets.
Here's an example of how you can do this:
---
import type { ImageMetadata } from 'astro';
import { Image } from 'astro:assets';
interface Props { imagePath: string; altText: string; name: string; age: number;}
const { imagePath, altText, name, age } = Astro.props;
const images = import.meta.glob<{ default: ImageMetadata }>('/src/assets/*.{jpeg,jpg,png,gif}');
if (!images[imagePath]) throw new Error(`"${imagePath}" does not exist in glob: "src/assets/*.{jpeg,jpg,png,gif}"`);
---
<div class="card">
<h2>{name}</h2>
<p>Age: {age}</p>
<Image src={images**imagePath** ()} alt={altText} class="common-class-name" />
</div>
In this example, images is an object that contains all of the image paths inside the assets folder. The imagePath prop is a string that contains the path to the image that you want to display. The import.meta.glob() is doing the work of finding the image path that matches the imagePath prop and handling the import for you.
You can then use this component in an Astro page, passing in the values for the props:
---
import MyCustomCardComponent from '../components/MyCustomCardComponent.astro';
---
<MyCustomCardComponent imagePath="/src/assets/avatar-1.jpg" altText="A headshot of Priya against a brick wall background." name="Priya" age={25}/>
In this case, each image can have a different altText as it's passed as a prop to the component. The class name is common as it's hardcoded in the component.
Remember to always provide an alt attribute for accessibility. If the image is merely decorative, set alt="" so that screen readers know to ignore the image (source (https://docs.astro.build/en/guides/images#alt-text)).
Also, the <Image /> component accepts all properties accepted by the HTML <img> tag, so you can provide a class to the final <img> element (source (https://docs.astro.build/en/guides/images#additional-properties)).

Let me check the knowledge base for you. One moment! :books:
To add srcset to your images in Astro, you can use the densities property of the <Image /> component. This property can be used to generate a srcset attribute based on pixel density descriptors.
Here's an example of how you can do this:
---
import type {{ ImageMetadata }} from 'astro';
import {{ Image }} from 'astro:assets';
interface Props {{ imagePath: string; altText: string; name: string; age: number;}}
const {{ imagePath, altText, name, age }} = Astro.props;
const images = import.meta.glob<{{ default: ImageMetadata }}>('/src/assets/*.{{jpeg,jpg,png,gif}}');
if (!images[imagePath]) throw new Error(`"${{imagePath}}" does not exist in glob: "src/assets/*.{{jpeg,jpg,png,gif}}"`);
---
<div class="card">
<h2>{{name}}</h2>
<p>Age: {{age}}</p>
<Image src={{images**imagePath** ()}} alt={{altText}} class="common-class-name" densities={[1.5, 2]} />
</div>
In this example, densities={[1.5, 2]} is used to generate a srcset attribute with pixel density descriptors of 1.5x and 2x. This means that the browser will choose the appropriate image to display based on the pixel density of the user's device.
You can then use this component in an Astro page, passing in the values for the props:
---
import MyCustomCardComponent from '../components/MyCustomCardComponent.astro';
---
<MyCustomCardComponent imagePath="/src/assets/avatar-1.jpg" altText="A headshot of Priya against a brick wall background." name="Priya" age={{25}}/>
Please note that densities that are equal to widths larger than the original image will be ignored to avoid upscaling the image (source (https://docs.astro.build/en/guides/images#densities)).

@cold cosmos Import declaration conflicts with local declaration of 'Image'.
cold cosmosBOT
Let me check the knowledge base for you. One moment! :books:
The error message "Import declaration conflicts with local declaration of 'Image'" typically means that you're trying to import a module named Image while there's already a local variable or declaration with the same name Image.
In the context of Astro, you might be importing the Image component from astro:assets while there's already a local declaration with the same name. Here's an example that could cause this error:
---
import { Image } from 'astro:assets';
let Image = 'some other value';
---
In this case, you're trying to import Image from astro:assets and also declaring a local variable named Image. This causes a conflict because the names are the same.
To resolve this issue, you can rename either the imported module or the local declaration. Here's an example of how you can do this:
---
import { Image as AstroImage } from 'astro:assets';
let Image = 'some other value';
---
In this example, Image from astro:assets is renamed to AstroImage to avoid the naming conflict.

The error message "Type '{ src: Promise<{ default: ImageMetadata; }>; alt: { altText: string; }; class: string; densities: number[]; }' is not assignable to type 'IntrinsicAttributes & Props'. Property 'src' does not exist on type 'IntrinsicAttributes & Props'." typically means that the src property is not defined in the Props interface.
In your case, you're trying to pass a src prop to the Image component, but it's not defined in the Props interface.
To resolve this issue, you need to import the Image component from astro:assets and define the src property in the Props interface. Here's how you can do this:
---
import type { ImageMetadata } from 'astro';
import { Image } from 'astro:assets';
interface Props {
imagePath: string;
altText: string;
src: ImageMetadata;
}
const { imagePath, altText } = Astro.props;
const images = import.meta.glob<{ default: ImageMetadata }>('/img/art/*.webp');
if (!images[imagePath]) throw new Error(`"${imagePath}" does not exist in glob: "/img/art/*.webp"`);
---
<div class="card">
<Image src={images**imagePath** ()} alt={altText} class="common-class-name" densities={[1.5, 2]}/>
</div>
