You need to know the location on file system of the image.

If it’s an image from the Internet you can save it to the system tmp folder.

Then install the `image-size` [npm](https://flaviocopes.com/npm/) module

```javascript
npm install image-size
```

and you can use it like this:

```javascript
import sizeOf from 'image-size'

const { height, width } = sizeOf(fileLocation)
```
