Rails - Sep 2006 - acts_as_attachment with restful application, image_tag fails

i have the following routes:

  map.resources :categories do |category|
    category.resources :products do |product|
      product.resources :images
    end
  end

The A_A_A plugin works fine when uploading images. I can view the 
follwoing url to see details such as image size and the url''s for 
images:

category/1/product/2/images/2

When selecting the url for an image i can view the image at the 
following url:

http://localhost:3000/files/24/100_1256_thumb.JPG

THE PROBLEM:
When i add an image_tag to the show page to view the image i get the 
following error. Notice that it considers the category_id to be the url 
of the image.

DO i need to setup a resource for the image''s to be displayed ??



Error:
ActionController::RoutingError in Images#show
Showing app/views/images/show.rhtml where line #17 raised:

image_url failed to generate from 
{:category_id=>"/files/24/100_1256.JPG",
:action=>"show",
:controller=>"images"}, expected: {:action=>"show", 
:controller=>"images"}, diff:
{:category_id=>"/files/24/100_1256.JPG"}

Extracted source (around line #17):

14:
15:   <h4>Image</h4>
16:   <p>Original: <%= @image.filename %></p>
17:     <%= image_tag @image.public_filename, :size => @image.image_size 
%>
