Adding multiple images on a page with CRUD - ruby-on-rails

Question

I want to add several different images with a crud to make some "work pages" but i struggle with the way to do this. Do I have to update my model or how i can specify that each adding field is for a section of my view? I'm using cloudinary to host the images.
For now when I add an image its all the same but I wanted to add differents ones at each spot.
My work#new view :
<div class="container text center">
<%= simple_form_for(#work) do |f| %>
<div class="row justify-content-center">
<div class="col-md-6 col-sm-12">
<h1 class="heading-02" style="padding: 2rem 0rem;">New Work</h1>
<div class="work-new-section">
<h2 class="sub-heading-03">Header</h2>
<%= f.input :name %>
<%= f.input :description %>
<%= f.input :photo, as: :file %>
</div>
<div class="work-new-section">
<h2 class="sub-heading-03">Tasks</h2>
<%= f.input :task_title %>
<%= f.input :tasks %>
<%= f.input :photo, as: :file %>
</div>
<div class="work-new-section">
<h2 class="sub-heading-03">Content#1</h2>
<%= f.input :content1_title %>
<%= f.input :content1 %>
<%= f.input :photo, as: :file %>
</div>
<div class="work-new-section">
<h2 class="sub-heading-03">Focus</h2>
<%= f.input :focus_title %>
<%= f.input :focus %>
</div>
<div class="work-new-section">
<h2 class="sub-heading-03">Content#2</h2>
<%= f.input :content2_title %>
<%= f.input :content2 %>
<%= f.input :photo, as: :file %>
</div>
<%= f.submit 'Create a new Work', :class => 'button-accent mb-4' %>
</div>
</div>
<% end %>
</div>
Work#new
My Work model :
class Work < ApplicationRecord
has_one_attached :photo
end
For the work#show is use some partials with the same behaviour in it:
<div class="container">
<div class="row">
<div class="col-md-4 col-sm-12">
<%= cl_image_tag #work.photo.key, :class=> "work-image", :width => 420, :height => 236, :crop => "fill" %>
</div>
<div class="col-md-4 col-sm-12">
<h2 class="sub-heading-03"><%= #work.content1_title %></h2>
<p class="ui-regular-01"><%= #work.content1 %></p>
</div>
</div>
</div>
Work#show
How could I specify one particular photo to each section? (task, content#1, content#2 etc...)
Thank you very much for your time!
I tried to change my new view but i have the impression that i omit something that i don't understand very well.
