You first need to create thumbnails for the images, likely using something like Google Cloud Functions or Google App Engine. You can write a function that takes the original image, and runs it through ImageMagick, then saves it back to Firebase Storage at a known location, say images/myImage_resized_<height>_<width>.png, which your client can then fetch.
Alternatively, you can use Imgix or Cloudinary to serve smaller images stored in Firebase Storage by providing our Download URLs to those services and fetching the images from there. If you're willing to do some more work, Google App Engine offers the App Engine Images API for free, which does many of the same things.
