If an image has `alt`, the screen reader will say: *"image: company logo"* instead of *"image: empty"*. 2. **Conveys meaning, not just "something is here"** This is especially critical when the image is part of navigation, a button, a chart, or infographics. 3. **Respects the user** Without `alt`, an interface becomes inaccessible. Which means unethical, non-functional, and formally non-compliant (for example, with the WCAG standard). --- ### For SEO: 1. **The search engine does not "see" the picture, it reads** `alt` A bot analyzes the text in `alt` to understand what is depicted: a product, a diagram, an object. This affects indexing and appearance in Google Images. 2. **Helps associate the image with keywords** For example, a product with `alt="blue men's winter jacket"` has a higher chance of ranking for the query *"blue men's jacket"*. 3. **Works as part of the text content** `alt` can add weight to a page's key topics, especially when the image is contextual and complements the article. --- **Conclusion:** The `alt` attribute is **eyes for those who cannot see**, and **language for those who cannot understand pictures**. Its absence is like a file with no name: it exists, but no one knows why.For the reviewerNote to the moderator (optional)Visible only to the moderator. Helps review go faster.
