What is a metadata tag used for images?

• A. File size metadata of the image to optimize loading times.
• B. Alt text describes the image for accessibility and can help with image SEO.
• C. Alt text is used to crop the image.
• D. Alt text is used only for decorative images.

Answer: (B)

Alt text is the metadata tag most appropriate for describing images. It communicates what the image shows to users who can’t view it (through screen readers) and helps search engines understand the image content for indexing, boosting image SEO. It also serves as a fallback if the image fails to load, improving the user experience. Cropping is an editing action, not a metadata description, so that option doesn’t fit. Alt text isn’t limited to decorative images—the guidance is to use descriptive text for meaningful images (decorative images may use empty alt text)—so the idea that it’s only for decorative images isn’t correct. The notion of metadata describing file size to optimize loading times isn’t about content description, so that choice isn’t about the typical metadata tag used for images.
