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 module

npm install image-size

and you can use it like this:

import sizeOf from 'image-size'

const { height, width } = sizeOf(fileLocation)
