Proxy images through a Rails controller

image_proxy_controller.rb

require 'base64'
require 'net/http'

class ImageProxyController < ActionController::Base
  def get
    url = URI.parse(Base64.decode64(params[:url]))
    image = Net::HTTP.get_response(url)
    send_data image.body, type: image.content_type, disposition: 'inline'
  end
end

routes.rb

Rails.application.routes.draw do
  get '/image_proxy/:url', to: 'image_proxy#get'
end

Thanks. This works great!
