The agent successfully navigates to the 'Media' section on a11y-style-guide.com. The agent successfully locates the 'Images' subsection within the 'Media' section. The agent states that the 'alt' attribute should contain a brief and accurate description of the image's content or purpose, providing equivalent information for users who cannot see the image. The agent explains that 'aria-describedby' is used to provide a longer, more detailed description for complex images (e.g., charts, graphs), linking the image to an element (like a paragraph or section) containing that extended description.
