Using a url
```javascript var url = require('url'); var http = require('http'); var sizeOf = require('image-size'); var imgUrl = 'http://my-amazing-website.com/image.jpeg'; var options = url.parse(imgUrl); http.get(options, function (response) { var chunks = ; response.on('data', function (chunk) {
chunks.push(chunk);
}).on('end', function() {
var buffer = Buffer.concat(chunks);
console.log(sizeOf(buffer));
}); }); ``` You can optionally check the buffer lengths & stop downloading the image after a few kilobytes. You don't need to download the entire image
