This is a list of image sources for a responsive image. Let’s break down what it means:
/next/image/?url=https%3A%2F%2Fs3-eu-west-1.amazonaws.com%2Fprod-media-racingpost%2Fprod%2Fimages%2F1691008%2Fc08303b8da11-2000-free-bets-1920x1080.jpg: This is the base URL for the image. It points to an image hosted on an Amazon S3 bucket (s3-eu-west-1.amazonaws.com) belonging to “racingpost”. The actual image file is c08303b8da11-2000-free-bets-1920x1080.jpg.
&w=...: This is a query parameter that specifies the width of the image. The image is being served in multiple sizes.
&q=75: This is a query parameter that specifies the image quality. A value of 75 indicates a quality level of 75% (lower values mean smaller file sizes but perhaps more compression artifacts).
48w, 64w, 96w, ... 2048w: Thes are the different widths the image is available in.
In essence, this is a set of URLs for the same image, but optimized for different screen sizes and resolutions. A modern web browser (or a framework like Next.js,which is likely being used here) will use this list to choose the most appropriate image size to download based on the user’s device and screen. This is called responsive images and it’s a key technique for improving website performance and user experience.
What the code is doing:
The code is providing a list of image URLs wiht varying widths. The browser will then select the most appropriate image based on the device’s screen size and pixel density. This ensures that the user downloads an image that is large enough to look good on their screen, but not so large that it wastes bandwidth.
Example:
If a user is viewing the page on a small mobile phone,the browser might choose the 48w or 64w image.
If a user is viewing the page on a large desktop monitor, the browser might choose the 1920w or 2048w image.
