When an image is the only content of a link, it should specify alternative text, 
via an `alt` attribute. The alternative text should describe the purpose of the link.

Without this, some users will be unable to determine what a link does, for example anyone 
using a screen reader.

To fix this, simply add an `alt` attribute to the image inside the link, e.g.:

```html
<a href="/apple">
    <img src="apple.png" alt="Apple">
</a>
```
