Code Review
This pull request successfully optimizes image handling by replacing standard <img> tags and CSS background images with the Next.js <Image> component. The changes are well-implemented and correctly leverage features like fill, sizes, and priority for better performance and reduced layout shift. The addition of unit tests is also a great step to ensure these changes are working as expected. My feedback focuses on improving maintainability by suggesting the extraction of inline styles into CSS classes.

For better maintainability and separation of concerns, consider moving these inline styles to CSS classes. This will make the component's structure cleaner and the styles easier to manage and reuse across the application.
For example, you could define classes in your stylesheet and apply them here:
CSS:
.background-container {
position: relative;
}
.background-image {
object-fit: cover;
z-index: -1;
}
.content-container {
position: relative;
z-index: 1;
}JSX:
<div className="team8-section-rea sp1 background-container">
<Image ... className="background-image" />
<div className="container content-container">
{/* ... */}
</div>
</div>| <div className="img1 image-anime" style={{ position: "relative", aspectRatio: "250/307" }}> | ||
| <Link href={`/${year}/speakers/${speaker.id}`} style={{ display: "block", position: "relative", width: "100%", height: "100%" }}> | ||
| <Image | ||
| src={speaker.profilePicture || "/assets/img/all-images/team/team-img28.png"} | ||
| alt={speaker.fullName} | ||
| fill | ||
| sizes="(max-width: 575px) 100vw, (max-width: 991px) 50vw, (max-width: 1199px) 33vw, 25vw" | ||
| style={{ objectFit: "cover" }} | ||
| /> | ||
| </Link> | ||
| </div> |

Similar to the background image, the inline styles used for the speaker images and links could be extracted into dedicated CSS classes. This would improve the readability of the component and centralize styling logic, making future updates easier.
Here's an example of how you could structure this:
CSS:
.speaker-image-wrapper {
position: relative;
aspect-ratio: 250 / 307;
}
.speaker-image-link {
display: block;
position: relative;
width: 100%;
height: 100%;
}
.speaker-image {
object-fit: cover;
}JSX:
<div className="img1 image-anime speaker-image-wrapper">
<Link href={...} className="speaker-image-link">
<Image
...
className="speaker-image"
/>
</Link>
