### Why is this important?
When an image contains important information unavailable in text on the page, providing a text alternative makes the same information accessible through audio or other channels.
<!-- This is where the code snippet is injected -->
<div id="locSnippet"></div>
### What to do
* If the image conveys meaning, the value of the `"alt"` attribute should be a short description that serves the same purpose as the image. Include any important words from the image in the short description (e.g., `<img alt="submit">`). Do not use a file name.
* **Or**, if the image is decorative or the same information is also available in text, use the `"alt"` attribute with an empty string as its value (e.g., `<img alt="">`).
