#Blurry images when using next image
velvet abyssBOT
The blurriness of your images when using the next/image component could be due to a few reasons. Here are some steps you can take to prevent this:
- Ensure Correct Image Dimensions: Make sure you're providing the correct
widthandheightprops to thenext/imagecomponent. These attributes are used to infer the correct aspect ratio of the image and avoid layout shift from the image loading in. They do not determine the rendered size of the image file. If you're using remote images, you'll need to provide these props manually. Here's an example:
<Image
src="<https://s3.amazonaws.com/my-bucket/profile.png">
alt="Picture of the author"
width={500}
height={500}
/>
Source (https://nextjs.org/docs/pages/building-your-application/optimizing/images)
-
Use Modern Image Formats: The
next/imagecomponent automatically serves correctly sized images for each device, using modern image formats like WebP and AVIF. These formats offer better compression and quality characteristics compared to older formats like JPEG and PNG. -
Custom Image Loader: If you're using a cloud provider to optimize images instead of the Next.js built-in Image Optimization API, you can configure a custom
loaderFilein yournext.config.js. This file must export a default function that returns a string. Here's an example:
module.exports = {
images: {
loader: 'custom',
loaderFile: './my/image/loader.js',
},
}
And the loader file:
export default function myImageLoader({ src, width, quality }) {
return `<https://example.com/${src}?w=${width}&q=${quality> || 75}`
}
Source (https://nextjs.org/docs/pages/api-reference/components/image)
Remember, the next/image component extends the HTML <img> element with features for automatic image optimization. If you're still experiencing issues, you might want to check the full image configuration documentation (https://nextjs.org/docs/app/api-reference/components/image#configuration-options) for more information.

Lets say I have an image with a width of 160px and height of 50px
Write the <Next /> component with props

Let me check the knowledge base for you. One moment! :books:
Sorry @fair jackal, I seem to be having a bit of trouble. Don't worry though, I've pinged my supprt and they will try to fix me up! :technologist:
Perhaps try again in 15mins?

Sure, here's how you can use the next/image component with an image of width 160px and height 50px:
import Image from 'next/image'
export default function MyComponent() {
return (
<Image
src="/path-to-your-image.png" // replace with your image path
alt="Description of the image" // replace with your image description
width={160}
height={50}
/>
)
}
In this code, replace "/path-to-your-image.png" with the actual path to your image, and "Description of the image" with a brief description of the image for accessibility purposes.

Let me check the knowledge base for you. One moment! :books:
The sizes prop in the next/image component is optional and it's used to provide information about how wide the image will be at different breakpoints. It can greatly affect performance for images using fill or which are styled to have a responsive size.
The sizes prop serves two important purposes:
-
It's used by the browser to determine which size of the image to download, from
next/image's automatically-generated source set. If you don't specify asizesvalue in an image with thefillproperty, a default value of100vw(full screen width) is used. -
It configures how
next/imageautomatically generates an image source set. Ifsizesis defined, a large source set is generated, suitable for a responsive image. If thesizesproperty includes sizes such as50vw, which represent a percentage of the viewport width, then the source set is trimmed to not include any values which are too small to ever be necessary.
Here's an example of how to use the sizes prop:
import Image from 'next/image'
export default function Page() {
return (
<div className="grid-element">
<Image
fill
src="/example.png"
sizes="(max-width: 768px) 100vw, (max-width: 1200px) 50vw, 33vw"
/>
</div>
)
}
In this example, without the 33vw sizes, the image selected from the server would be 3 times as wide as it needs to be. Because file size is proportional to the square of the width, without sizes the user would download an image that's 9 times larger than necessary.
So, if you know your image will be displayed at different sizes based on the viewport width, you should include the sizes prop. If your image will always be displayed at the same size regardless of the viewport width, you may not need to include the sizes prop.

@velvet abyss Lets say the rendered image will always be 80x25
What should my sizes me?
velvet abyssBOT
Let me check the knowledge base for you. One moment! :books:
If your image will always be rendered at a fixed size of 80px by 25px regardless of the viewport size, you technically don't need to use the sizes prop. This is because the sizes prop is used to inform the browser of how the image size will change based on different viewport sizes.
However, if you still want to use the sizes prop for some reason, you can set it to the fixed width of the image. In your case, that would be 80px. Here's how you can do it:
import Image from 'next/image'
export default function MyComponent() {
return (
<Image
src="/path-to-your-image.png" // replace with your image path
alt="Description of the image" // replace with your image description
width={160}
height={50}
sizes="80px"
/>
)
}
Remember to replace "/path-to-your-image.png" with the actual path to your image, and "Description of the image" with a brief description of the image for accessibility purposes.

@velvet abyss Does setting sizes for fixed width images help with saving bandwidth?
velvet abyssBOT
Let me check the knowledge base for you. One moment! :books:
No, setting the sizes prop for fixed width images does not help with saving bandwidth. The sizes prop is used to inform the browser about how the image size will change based on different viewport sizes. It helps the browser to select the most appropriate image source from the source set, which can help to save bandwidth when dealing with responsive images.
However, if your image has a fixed width and does not change size based on the viewport, the browser will always select the same image source regardless of the sizes prop. Therefore, setting the sizes prop for fixed width images will not have any effect on bandwidth.
If you want to save bandwidth, you should ensure that your images are properly optimized. The next/image component from Next.js can help with this, as it provides features for automatic image optimization.
