Using alt attributes for images in HTML is crucial for enhancing accessibility. When images are displayed on a webpage, visual content can be lost to users who may be visually impaired or using screen readers. The alt attribute provides a text description of the image, which screen readers can vocalize, allowing users to understand the context and content of the image even if they cannot see it. This aligns with best practices and standards for web accessibility, helping to ensure that all users, regardless of their abilities, can access information effectively.

While the other options touch on relevant aspects of web development, they do not encapsulate the primary purpose of alt attributes. For instance, although there are aspects of SEO linked to alt text, that is not the main intent behind its use. The focus should be on providing a user-friendly experience for those with visual disabilities. Additionally, the speed of image loading and improvement of visual quality are unrelated to alt attributes since these elements do not impact loading times or visual enhancement directly.
