Amazing! This package is what i use to verify an image's width and height in a very simple step.

You are requiring the getImageSize() and simply pass in your image file.

I would create a demo page to place here soon ... Demo

Add the Package using npm

To install, use:

npm install simple-image-size # or yarn simple-image-size

First Import the package, import getImageSize from 'simple-image-size' or Import the package, const getImageSize = require('simple-image-size') The is an async operation so you can use async/await or then/catch to get a promise Object with the image's width and height. You can use it by passing the image file as the only parameter to getImageSize(file).

valid IAB images is tested for jpg, png, gif.
