When you write an alt you should have a few things in mind. One of this thing suggests using an empty `alt=""` when the **image** content is **decorative** or contain a **repetitive information**.

But what the difference between using:

```
<img alt=""
<img aria-hidden="true"
<img role="presentation"

```

Or all together?

```
<img alt="" aria-hidden="true" role="presentation" src="…" />

```
