# Image button has no alt text

`a11y/input-image-alt` · severity **error** · category Accessibility · detected by `void a11y` and `void audit`

## Why it matters

An image button without alt text is announced by its file name or not at all, so screen-reader users cannot tell what it submits.

## How to fix it

Add alt text that describes the action (not the picture).

## Example

```
<input type="image" src="/search.svg" alt="Search">
```
