I want to add images and save url to mongodb

I have a project running on heroku, and I want in my form where I add new items to add images that will be directly saved in the public folder on the heroku app and the url to be saved in the Mongo database(so I can pick it up later to src the image). How should I do this ? maybe also with cropping the image to a fixed ratio.
