Uploading Multiple Images In Rails Using Loop

Hello I have 2 models Products and ProductImage. Product has_many ProductImages. I am using paperclip gem.

As you can see below in my binding.pry I have an array of the images locally. How do i upload these images and make a ProductImage. If i continue i get an error No handler found for "20090a.jpg"

    69: def create_product_images
 => 70:   binding.pry
    71:   params["product_images"].each do |image|
    72:     ProductImage.create(product_image: image, product_id: @form.product.id)
    73:   end
    74: end

[1] pry(#<ProductsController>)> params["product_images"]
=> ["20090a.jpg", "780069_black_l.jpg"]
[2] pry(#<ProductsController>)> @form.product.id
=> 16
[3] pry(#<ProductsController>)>

product_image.rb

class ProductImage < ActiveRecord::Base
  belongs_to :product

  has_attached_file :product_image, styles: { large: "600x600", medium: "250x250", thumb:"100x100#"}
  validates_attachment_content_type :product_image, content_type: /\Aimage\/.*\Z/
end

Here is my Product Create Action. Its not very good. There will be alot of refactoring. As you can see after the @form.save i have the create_product_images method which is shown above in the first snippet.

  def create
    @form = ProductForm.new(
      product_image: product_params[:product_image],
      title: product_params[:title],
      price: product_params[:price],
      size_description: product_params[:size_description],
      shipping_description: product_params[:shipping_description],
      description: product_params[:description],
      tag_list: product_params[:tag_list],
      category_id: product_params[:category_id],
      sizes_by_id: product_params[:sizes_by_id],
      user: current_user
    )
    if @form.save
      create_product_images
      redirect_to @form.product
      flash[:success] = "You have created a new product"
    else
      flash[:danger] = "Your product didn't save"
      new
      render "new"
    end
  end
